* myFC Puck: 1400 mAh (5,18 Wh)Перезаряжается в этом myFC + Trekk только LiPo. Топливная ячейка — www.powerguy.cz/fotky20450/fotov/_ps_361myFCQuestions-Answers2013.pdf — традиционный одноразовый PEMFC («Polymer Electrolyte Membrane Fuel Cell (PEMFC).… FuelCellSticker» = Proton exchange membrane fuel cells). Русский термин — Топливные элементы с протонообменной мембраной (multitran).
* Internal battery: Lithium Polymer 3800 mAh (14,06 Wh)
The Puck contains: Sodium Silicide, Sodium Borohydride and 12 g Aluminum (= 1 x 33 cl soda can). Therefore we recommend that you throw the used Puck in the recycling bin for Metal, whenever possible.
How does the Puck work?
The myFC PowerTrekk uses a fuel cell to convert hydrogen gas and oxy-
gen into usable energy. The hydrogen needed for this process is generated
within the Puck. Each Puck contains two water-reactive materials—sodi-
um silicide (NaSi) and sodium borohydride (NaBH4). Both materials in the
mixture are non-toxic and chemically stable in ambient temperature and
pressures. 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
sources 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 hydogen
generation process will stop.
Although it's yet to be confirmed, a MyFC spokeswoman told me the pouch unit should cost around $99 — that's roughly £65 or AU$130 — and a cartridge somewhere in the region of $2 — that's roughly £1.50 or AU$2.50. The idea is that you'd buy cartridges in multipacks, perhaps nine for $10.
