e-Cell enclosed hydrogen fuel cell now available !

[hartiberlin]

Hi All,
check out this new enclosed hydrogen fuel cell battery,
simular to NiMh batteries but with a more constant output voltage:

Already now available.

I really would like to try them, so I have to see, if I can get them
in Germany too.

Regards, Stefan.

Now this is my favorite kind of technology...
Why bother with an electrolyzer and fuel cell when you can hybrid them.
I'm trying to find out more about their life span now, but if they can last a few
years and get power to weight ratio of hydrogen powered auto and electronics
a little higher it will hopefully become more feasible. Altho the real problem with
hydrogen fuel cells today is the cost! So I'll also be attempting to purchase some
of these. I hope they don't cost an arm and a leg.

I hope someone developes a 24V high Ah model soon...
Now that would be some cool plug and play technology!
POOF! Your scooter is hydrogen powered!

They are actually pretty cheap:

Hmm, are this really fuel cells or are these just special NiMH
batteries ?

Well he did say it was a nickel metal hydrate battery design, but it is overtly advertised as a hydrogen technology. I assume it's like most NiMH batteries.

Anode material is nickel alloyed with vanadium, zirconium, titanium and chromium.

anode: MH(s) + OH-(aq) = M(s) + H2O(l) + e-
cathode: NiOOH(s) + H2O(l) + e- = Ni(OH)2(s) + OH-(aq)

But the problem with normal NiMH batteries is that hydrogen gas will slowly
build up and the electrodes begin to oxidize in place of the missing hydrogen.

We'll just have to see if someone posts some chemistry data on these things.

In the mean time though their 8pk AA rechargables are going for 1$ a watt.
Not exactly something you would want to run a scooter on yet.

EDIT: That came out wrong... They're awesome for portable electronics now,
but just not feasible for a electric scooter in the 1.5 volt AA cell form. LOL!
