Cheap fuel cell from H2 gaseous water ?
« on: September 03, 2007, 07:14:17 AM »
Hi All,
I had a new idea how to build even cheaper fuel cells,
that convert hydrogen to electrical energy.

The problem modern fuel cell still have is,
that they need real Hydrogen gas, so you must store
the hydrogen gas somehow, e.g. in a metalhydrid container
or just produce it on demand from solar energy, but which
is not possible during night time...
So I came up with a simular system idea like the Steven Ryan
Why not store the hydrogen in water as gased water, like
we store CO2 in water as selter water... ?

The same can be done with oxygen.

Now use H2 stored in water and O2 stored in water
and just put H2 stored in water in one container containing
platinized nickel mesh ( or platinized graphite beads)
and put O2 stored in water into another container having
platinized nickel mesh ( or platinized graphite beads).
Then use a diaphragma where ions can travel through to
connect these 2 containers
(or just use a graphite bridge to connect them)
and voila you have the easiest
fuel cell !
The good thing about it is, that you only have to feed it
with these 2 gased liquids.
You can easily produce the H2 and O2 containing water
from electrolysis by using an electrolysis cell, that seperates the
gases during production and the buildup pressure and bubble
it with pressure into air-poor water..

Thus the H2 or O2 will go into solution into the water and
this will be then like "selters" water which can fuel the fuel-cell
electrodes easily.

No more need for an Alkaline solutions in a fuel cell.

Also with better and cheaper catalysts than Platinum
this technology will get much more cheaper and thus
the solar energy can be stored easily inside water !
No more big hydrogen tanks, no more liquid hydrogen tanks..

So H2 and O2 gaseous water could be a good fuel storage
for the solar power industry !
Just bottle this water up like selter water which you can
buy in a supermarket...

Regards, Stefan.

P.S. if you put the second electrode just into the air,
you could just power this fuel cell just with gaseous
H2 water.
The other electrode would pull the oxygen just from the
So you would only need to get a bottle of gaseous H2 water to
drive and refill your fuel cell !

Best regards, Stefan.

G'day Stefan,

I am just wondering whether you can store meaningful amounts of Hydrogen gas in water. CO2 can be stored in appreciable quantities if the water is cold enough when you put it in. After that it has to be well capped since it will go out of solution at ambient temperatures.

I have never tried it with Hydrogen. Do you have any data, I would be interested.
