Yes.

I have lost the water tank lid, cable etc How can I get replacements?

Don’t worry, contact myFC support for assistance, support@myfc.se.

Does it start to charge immediately after I've inserted water and a puck?

Yes, within sixty seconds. If the fuel cell has been dehydrated it may take longer

Why is water needed in the process?

Water (H2O) is made of Oxygen (O) and Hydrogen (H2). The Sodium Silicide (NaSi) in the Puck is used to liberate the Hydrogen from the water
2 NaSi + 5 H2O -> 5 H2 + Na2Si2O5


The myFC Pucks

How do I store the myFC Puck?

Store the myFC Puck in a cool and dry location.

Never use a Puck that is not stored in an aluminum bag. Pucks stored in a 3-pack paper gift box should not be used. If you have Pucks packaged like this - please contact support@myfc.se and we will change them for you.

What is the shelf life of a myFC Puck?

Two years from manufacturing date. Manufacturing date is printed on the Puck package.

Can I re-use or re-load a Puck?

No, the myFC Puck is one time use only. Do not try to restart. Also do not tamper or try to open the Puck. Never insert a used or partially used Puck in the myFC PowerTrekk. Reusing the Puck may cause the Puck to overheat, contents to leak, or irreversible damage to your fuel cell charger.

Are the Pucks re-chargeable?

No the myFC Puck is one time use only. Do not try to restart. Also do not tamper or try to open the Puck

What should I do with the Puck once it has been used?

Make sure the Pucks have cooled off before disposal or shipping preferably recycle them as metallic waste or if that is not an option, throw them in the bin. Consult local regulation and policies to ensure as low environmental impact as possible.

What is myFC Puck made of?

The body of the Puck is an aluminum can that holds the binary fuel, Sodium silicide and Sodium borohydride (CAS number: 12164-12-4 & 16940-66-2). The aluminum can is then permanently attached to a plastic cap, which is used to control the release of hydrogen gas to the fuel cell. After the fuel mixture is fully reacted, the Puck will contain two benign by-products (sodium silicate and sodium metaborate).
Both by-products are chemically benign, non-hazardous, and safe. In fact, these by-products are used in many industrial manufacturing processes and many common household products (like concrete, detergent, glass, makeup, and toothpaste) are produced using these materials.

How does the Puck work?

The PowerTrekk uses a fuel cell to convert hydrogen gas and oxygen into usable energy. The hydrogen needed for this process is generated within the Puck. Each Puck contains two water reactive materials —sodium silicide (NaSi) and sodium borohydride (NaBH4). The mixture that is stored within the Puck is a solid powder; when water is delivered into the Puck, it initiates a chemical reaction that produces the hydrogen needed by the fuel cell.

While both of these materials will individually generate hydrogen, each generates the hydrogen differently. Sodium silicide extracts the hydrogen externally from the water (H2O), while the sodium borohydride breaks the hydrogen bonds that are internal to the compound (BH4). When the hydrogen generation process begins within a Puck, the sodium silicide is the first material to produce hydrogen. Sodium silicide generates hydrogen according to the following chemical reaction:

2 NaSi (solid) + 5 H2O (liquid) → 5 H2 (gas) + Na2Si2O5 (aqueous) + Heat

The heat that is generated by the sodium silicide reaction is then used to initiate the sodium borohydride reaction process according to the following chemical reaction:

Heat + NaBH4 (solid) + 2 H2O (liquid) → 4 H2 (gas) + NaBO2 (aqueous)

The two materials generate hydrogen simultaneously until the mixture is fully depleted. If the delivery of water is halted during this process, the hydrogen generation process will stop.

What is the weight of a myFC Puck?

30 gram

What is the size of a myFC Puck?

Puck dimensions (mm): 20x51



Safety

What happens if I break the Puck and content comes out (not on skin or clothes)?

If the Puck should break and content spills out, DO NOT pour any type of liquid on it (NO WATER) and avoid all potential ignition sources. Carefully scoop up the spilled materials and place in an appropriate container for disposal. In the unlikely event of a Puck rupture, in no circumstances should ones face be over or near the Puck. First remove Puck content with a dry cloth or paper tissue, and then rinse heavily with water if suitable.

What happens if I break the Puck and content comes in contact with clothes or skin?

If the Puck should break and content spills out, DO NOT pour any type of liquid on it (NO WATER) and avoid all potential ignition sources. First remove Puck content with a dry cloth or paper tissue, and then rinse heavily with water. If contents get in contact with eyes or mouth rinse immediately with water and get in contact with medical doctor or hospital.

Are there any situations where the myFC PowerTrekk could be dangerous?

The myFC PowerTrekk is completely safe when you use it appropriately. Should you tamper with or break the Pucks it is important not to get the get the Puck’s content in contact with your skin. Should that happen, rinse carefully with plenty of water. If content comes on any other surface, wipe off with a dry cloth or paper tissue. If there is a risk of hydrogen emissions an alarm will indicate that you should separate the Engine and the Tray to stop the hydrogen generation.

What safety precautions are there for the myFC PowerTrekk?

The myFC PowerTrekk contains a Lithium Polymer battery (1500mAh), referred to as the Internal Battery. Use only the prescribed method to charge the Internal Battery; never try to use any other charging method. Avoid contact with contents. Contents are corrosive, toxic and flammable. Never expose to high temperatures or open flames. Keep away from children.

DO NOT disassemble, pierce or subject your myFC PowerTrekk to shock. Content may contain flammable gas. Use only with the myFC certified myFC Puck.

What safety precautions are necessary for the Puck?

During operation the myFC Puck may be very warm. DO NOT touch the Puck with your bare hands during operation or directly after use. If you drop the Mobile Charger during operation and the Puck falls out, use protective cloth or gloves to prevent skin burn.

The myFC Puck is a SINGLE USE unit and SHOULD NOT be reused. Once a Puck has been inserted it is considered as used. NEVER restart your myFC PowerTrekk with a used Puck.

Never expose to high temperatures (above 70°C) or open flames.

Keep away from children.

The myFC Pucks shall be stored in a cool and dry location.

What happens if the content in the puck comes in contact with water?

Hydrogen will be generated immediately once the fuel mixture is exposed to water. The hydrogen generation process is designed to be isolated and wholly-contained within the Puck. The Puck itself is waterproof; if water comes in contact with the outside of the Puck there will be no reaction.

However, if the contents of a Puck are ever spilled and they then come into contact with water, the hydrogen reaction will begin. If a heat source is present, there is the possibility of ignition.

If a Puck is ever disassembled through misuse, please follow all instructions listed above for safe handling in such a scenario and avoid all potential contact with water or any other type of liquid.

Why does some of the Pucks emit a smell, is it harmful?

In the initial phase of the hydrogen generation inside the myFC Puck a quick pressure increase may happen. To reduce pressure the relief valve will open up for a short moment. At this point you may sense an alkali smell. The recommendation is to use the myFC PowerTrekk in well ventilated areas.

What happens if someone opens a Puck?

The myFC PowerTrekk is completely safe when you use it appropriately. Should you tamper with or break the Puck it is important not to get the get the Puck’s content in contact with your skin. Should that happen, wipe off content thoroughly and carefully with a dry cloth or paper tissue. Then rinse with plenty of water. Be careful not to get any of the content in your eyes or mouth.

Why must I store the myFC PowerTrekk charger in a sealed plastic bag?

All Fuel cells, including the myFC PowerTrekk, are sensitive to pollution, which is why we strongly recommend storing the myFC PowerTrekk inside a sealed plastic bag when not in use.

Can I bring the charger and the pucks on an airplane?

Yes.

Can I use the myFC PowerTrekk and the pucks on an airplane?

You can use your myFC PowerTrekk on an airplane. However, there are certain regulations regarding charging lithium-ion batteries on board a plane. Make sure you follow your airlines regulations before charging.

What happens if I add other fluid liquid than water in the myFC PowerTrekk?

For best performance, use fresh water between 5-35 °C. Preferably don’t use any other liquid than water (H2O) as the performance is in direct relation to the amount of water molecules in the fluid. myFC cannot guarantee that other fluids will not cause permanent damages to the Fuel cell.

What do I do if my myFC PowerTrekk runs hot to the touch?

When charging your electrical device, the myFC PowerTrekk may become warm. This is normal and is due to the heat produced by the Fuel Cell and the myFC PowerTrekk Puck. When energy is being produced, an increase in temperature is normal.



Technical

What is the energy output of myFC PowerTrekk?

The internal battery is 1500mAh and each myFC Puck is equivalent to 1200mAh. The power output is in Fuel Cell mode 2.5W and in Internal Battery Mode 5W. For both modes the output voltage is 5

How many AA-batteries do I need in order to get the same capacity as from one myFC Puck?

There are several kinds of AA-batteries on the market from different manufactures. All differ in capacity and price but normally, one AA-battery is capable of delivering 200-300 mAh at 5 V with a load of 2.5 W. The myFC Puck will give 1200 mAh at the same conditions which means that you need 6 AA batteries for each myFC Puck.

Why must I use the myFC cable and not my mobile phone cable?

Regulatory (CE, FCC etc) testing require a defined cable for validity. Moreover, most devices will accept a charge at 2.5W, however, Apple devices require up to 5W. While running the myFC PowerTrekk in Fuel Cell mode, the power output is limited to 2.5 W which needs to be signaled to the Apple device. This is achieved with the Apple 30-pin plug that is included in the package. myFC is aware of the increasing demands of power output and will take this into consideration for future products.

How long does it take to charge the internal battery from the grid?

It mostly depends on the size of the battery of your device. If your device has a 1350mAh battery and is normally charged at 2.5W (500mA at 5V) it will take 2 hours in Fuel Cell mode which should be the same as your standard charger. However, a modern smart phone will charged fully in twice the time with the myFC PowerTrekk in Fuel cell mode compared to a USB charger connected to the grid.

What is the size of myFC PowerTrekk?

Charger dimensions (mm): 66x128x47

What is the weight of the myFC PowerTrekk?

240 gram.

Does my myFC PowerTrekk come with different USB plugs?

Yes, myFC PowerTrekk comes with three different types of USB-plugs: mini USB, micro USB, Apple 30 pin and Apple 30-to-9 pin converter.

Why does myFC PowerTrekk have an internal battery?

myFC PowerTrekk is a hybrid fuel cell charger for portable electronics, equipped with an internal rechargeable Li-Po battery for energy storage. Equipped with an internal battery, the myFC PowerTrekk can also be used as an ordinary battery charger and you will be able to draw a maximum output power of 5 W. The internal battery is also very useful for taking care of the surplus energy of the Puck when you are done charging your device.

What is fuel cell technology and how does it work?

A fuel cell is an electrochemical device that transforms the chemical energy of a fuel (hydrogen, methanol, natural gas, gasoline etc.) and an oxidant (air or oxygen) into electrical energy. The fuel and the oxidant react at two different electrodes – the anode and the cathode – and are separated by an electrolyte that transmits ions (e.g. H+, OH- etc.) from one electrode to the other. Fuel cells have many similarities with batteries, but with the fundamental difference that the electrodes are not consumed in the process – a fuel cell will run as long as fuel and oxidant (air) is provided to the electrodes.

What is hydrogen?

Hydrogen is the lightest and most abundant chemical element, constituting roughly 75 percent of the universe’s chemical element mass. Today a large amount of hydrogen is used as raw material in industries. In the future hydrogen may also play an important role in society’s transformation from fossil fuels to renewable alternatives. Hydrogen powered fuel cells can power anything from cars and boats to cell phones and computers. They can also be used to supply electricity and to heat houses.

What do I do with my myFC PowerTrekk if it is no longer working?

The myFC PowerTrekk should be recycled as electronic waste according to local regulations.



Environment

Is myFC PowerTrekk environmental friendly?

Yes, myFC PowerTrekk is a green energy solution that makes green energy instantly available everywhere to everyone. The Puck contains no heavy metals as most disposable batteries do. One puck weighs similar to an AA-battery but contains effective energy corresponding to 6 AA-batteries

Are there any harmful by-products?

No, from the Fuel Cell the only by-product is water vapor. By-products from the myFC Puck, the by-product from the chemical reaction is sodiumsilicate and sodiumboroxide, materials which are used in landfill and cosmetical products. However, the by-products are basic and skin contact should be avoided.

How does hydrogen affects the environment?

Hydrogen is an alternative energy carrier to fossil fuels and oil. The magnitude of the environmental gains possible through the use of hydrogen as an energy carrier depends on how the hydrogen is produced and transported, as well as how efficiently it is transformed.

There are two primary areas where the environmental potential of hydrogen is especially significant; in transportation and as an interim storage of renewable energy.

Through the use of hydrogen together with fuel cell technology it is possible to achieve a radical decrease in local pollution of carbon dioxide, nitrogen oxides and particles from the transportation sector. Although the production of hydrogen from fossil fuels affects the environment it is an advantage that the carbon dioxide emissions can be separated already on the production site. This becomes evident when hydrogen is used as vehicle fuel, avoiding pollution from every individual vehicle.

The only emission from a fuel cell reacting with hydrogen is pure water. The environmental gains are high, provided that pollution in the hydrogen production process is kept low. A fuel cell is approximately twice as energy efficient as a combustion engine if used in a regular car. The effect is that, using the same amount of energy, a fuel cell car can drive twice as far as a car with a combustion engine can.

Modern batteries have even lower energy losses than those of fuel cells. However, these need to be recharged and are relatively heavy. Therefore, a combination of batteries and fuel cells can be advantageous in many areas, particularly in vehicles. For example, the reach of an electric car of family size is up to 500-600 kilometers of pollution free driving, since the fuel cells recharge the battery while the car is in use. A growing part of the transportation sector is the use of fuel cells as APU (Auxiliary Power Unit). This kind of support power aggregate is used due to the large amounts of energy required to run cooling, air conditioning and other systems found in trucks. Today, this is mostly powered by small diesel engines or by idling the main engine, both of which create pollution and noise. The possibility of using hydrogen as APU in aircraft and large motorboats is also being explored.

Furthermore, hydrogen is expected to play a leading role as support in the development of renewable energy systems. Solar, wind and wave power are by their nature uneven sources of energy. Methods for interim storage are required in order for them to have any real consequence in the future. Here, hydrogen could even out the effect and function as storage for surplus energy. This would increase the flexibility of energy systems such as wind power, and help to accelerate the expansion of renewable energy. Although hydrogen could be produced from fossil fuels, the powder inside the myFC Pucks (that liberates hydrogen in reaction with water) is not made from fossil fuel.
