Homemade graphite rod fuel cell
« on: July 17, 2007, 08:52:17 PM »
Here is a video, which shows at the end,
how 2 graphite rods can be used to generate about 2 Volts from
stored H2 and O2 gas inside of them by using electrolysis before.

http://www.youtube.com/watch?v=mibnOhczXEk

What I don?tyet understand, if indeed the stored gases are used up
or if they use up stored Ions like OH- and H+ ions.

Can a chemist have a look at it and tell us please ?

This might just be the same process that is going on in a super capacitor.

Regards, Stefan.

Unfortunately, I can't access youtube at work (I wonder why?) but do you think this little link may give a good example of what is going on? It uses two graphite electrodes.

http://www.bthc.edu.hk/~hchsu/chem_hp/chemanim/electrolysis/electrolysis.html

Let it load, then hit the play button. Gives the chemistry examples.

Okay, as I have already guessed, it can only be the H+ and OH-
ions, that still sit in the graphite crystal unrecombined, which are
charging up the graphite after the elecrolysis process.

That is no wonder, that nothing happened, when I tried to bring a graphite rod
into  H2 gas enriched  water and the other graphite rod into O2 enriched water,
that there did nothing happen.

We have to get the OH- and the H+ ions directly into the crystal matrix of the graphite
to get a fuel cell with voltage output.

In professional fuel cell this is done with plating graphite with a costly
platin catalysator.

So I wonder, what exactly the platin will do at the graphite ?

Will it split the H2 gas into H+ ions  at one graphite electrode
and at the other electrode will it split the O2 into OH- ions ?

We have a find a better and cheaper way to do this.

Maybe one could use just silver metal  atoms too and suck them
up into the graphite lattice ?

You can easily use a collaidal silver generator electrolyizer to
generate lots of very small silver atoms, that can be embedded
into the graphite lattice...

I will try this out next time I am at home and have some free time.

If somebody could still post a list of metal atoms or other materials, that act
still better than platinum or silver to split H2 and O2 gases into their
ions, I would be very grateful.


Many thanks.

Regards, Stefan.

Hi Stefan,

I know this subject is a bit dated, but I found a website that listed solubility of gases in water:

http://www.engineeringtoolbox.com/gases-solubility-water-d_1148.html

One of the gases listed was hydrogen. It gives a solubility of 0.0015g. of Hydrogen / liter of water at 25C.

This means that in one liter of water there are:(22400ml) X (0.0015moles H2) = 33.6 ml of hydrogen in a liter of water at 25C.
                                                                  (mole H2)

So if this hydrogen saturated water would be run through one of my hydrogen/air fuel cells it should give off a voltage (I think)

This would be an interesting experiment to try. I will boil a given amount of water for several minutes to drive out any dissolved gases, then bubble my excess hydrogen through the water as it slowly cools to room temperature. Then I will run the hydrogen saturated water through one of my fuel cells and see if I get a voltage reading. This would be VERY interesting, and a much safer way to store hydrogen.

I also wonder if a very thin layer of this water was placed in a dish, if it would actually ignite with a flame?

Of course I need to get my reactor going first. This should be in about a week.

I made an error. A mole of H2 gas weighs 2 grams not one gram. So the volume of gas dissolved in water is cut in half to approximately 16.8 ml of hydrogen gas per liter of water.

Sorry about that.

Hi Dave,
yes,please test this,
if you get your Reactor to work again.

I have been reading, that one can do a selfmade fuel cell
from graphite and very fine powered nickel powder.

Nickel then works as the catalyst and is not consumed.

Good luck.

Regards, Stefan.

in this video link i think he is making carbon (not sure). but the book he sells may have the answers your are looking for. if you could get a hold of Roy M. he should know for sure but i don't know if he even has a Email address. i do know that steven H. only wants to sell books. I have not been to the web site for some time. and i don't think he has an address either.
