Here's a rather simple diagram with animations...  there's a few other links
on various types.  Hope this helps.  Keep up the great work!

Anode on the WC side, and cathode on Zn side.
Both above the water line of course...

Hi all,

Been searching round for cheap source of stainless steel. Excellent site on ebay(link below) selling all kinds of metals in the UK. Worth a look...

I found this in my CRC "Handbook of Chemistry and Physics" (63rd Edition 1982-1983) (Now everyone knows how old I am lol) under "The Elements" section describing Platinum:

"Hydrogen and Oxygen explode in the presence of platinum."

Hmmmm, Biggs gave a warning that is good to keep in focus.

I didn't want to do fuel cell research anyway. lol.

Well I'm just giving a heads up, sitting back on the sidelines trying to be of some use ..I didn't want you to hurt yourself.. pure oxygen (even small amounts) will react with hydrogen and platinum so proceed with caution..

Hi All,

Its been frustrating the last couple of weeks trying to get my reactor to stop leaking around the large tungsten/carbide electrode. I have tried eight times of cleaning out the reactor and resealing around the electrode with cyanoacrylic and the curing agent (kicker). Each time I was able to get a good seal when plain water or the electrolyte solution was left standing overnight in the reactor; but each time after the hydrogen reaction began a leak always developed around the electrode. It always took a couple of hours, but each time the leak redeveloped, forming next to the electrode and finally breaking through the outer acrylic that sealed around it.

After all this time I believe I finally understand why this is happening. I believe it has to do with the temperature that this reaction occurs at. When I do the sealing around the electrode it is being performed at room termperature (around 20 degrees Celsius or 68 degrees Fahrenheit) and I always get a good seal as long as the reactor and solution temperature is around room temp. Once the reaction begins the solution and reactor temperature begin to drop. The metal electrode probably shrinks from the temperature drop faster than the acrylic and pulls away from the acrylic around it, thus opening a void that causes an electrolyte solution leak.

This is probably the cause, and I cannot think of a way to solve it with the present setup. There probably needs to be some type of "O" ring that goes around the electrode and is sealed with acrylic. Probably like a void in the acrylic that the ring fits into. This would expand and contract with the electrode and keep the seal integrity. I need to think about how to do this, or chuck the present design and try something else.

Some of the reactors made out of tupperware might be a possibility. I think Yikes has been doing some.

Sorry, just wanted to keep everyone updated. I have been working on this every day, and I still keep getting leaks. I need a way to solve this.

Thanks for your interest.
