Its been a while since I updated things. I did try coiling the "platinum" wire to no avail. I now fully beleive that the wire being 92% Pt and 8% Tungsten is just not enough to do anything. I bought some HEET brand anitfreeze which is listed as being 99% methanol. Didnt do anything at all. Perhaps the tungsten is retarding the catalyste action somehow? Having the wire in the cell actually makes things worse Im willing to bet its the tungsten.
Anyways, I have been doing much with my commerical fuel cell. Really neat!I got a solar cell on ebay for 7$ and boy it is nice. It was made by some small company selling their products on ebay, and aside from the great power output, it is constructed really well! Fully water proof. 6.5volts, 210mA. I leave it in partial sun so that I dont overvolt the fuel cell when run in electrolysis mode.
I built a small joule thief onto a nice proto board, and it powers 3 UV LEDs really well. I use it to light up my autunite at night for a night light The cell also directly runs alot of electric motors quite well too. Right now, Im using a 60mL syring to contain the gas. I pull a vacuum in the cell with another syringe. The thing leaks bad though, as the tubing i have is a tad to large for the ports on the cell. Water leaks have also rusted one of the electrodes a bit at the bottom. A large tank to store the gas, and a fuel cell stack could really be quite useful to power some things, like a fan to keep my room cool
I still do plan to try to methanol fuel cell some time when I get some money together. I really would rather opt for platinum coated nickel screen, rather than that mini fuel cell thing with the KOH electrolyte. Perhaps some Nafion membrane as well while im at it. It would seem this would work really well providing I was able to get a really good platinum coating on some nickel screen. From what I see, I dont know if the oxygen side even needs a catalyste. It seems its all about the hydrogen side. Pure O2 and "air" work equally well. I now have some pics of my fuel cell setup. I will post them soon, once I figure out how to! Matt
