Anyone savvy with Air Electrodes??? Thanks! =)
I'm posting this after having googled, of course...I work with DIY fuel cells using off the wall fuels. By far, the most expensive component of my FCs is the Air Electrode which I purchase from Electric Fuel Ltd. in Israel. The material was invented in 2008 (as far as I know) and EF were the ones who bought the patent (according to the inventor himself...sorry but his name eludes me).
Anyhow, I was wondering if anyone knows how to make good air electrodes. Something that would give me at least a vold in reference to the SHE (V=0) and a current density of up to a few hundred mA/aq cm...The stuff is basically this, from the electrolyte side to the air side: Separator paper, Carbon powder with Manganese or Cobalt catalyst mixed in (and a binder of some sort, I suppose), a Nickel mesh (current collector) and a bit more Carbon+catalyst then a microporous Teflon(r) sheet (permeable to gases but not to liquids).
I cant find nickel mesh where I live but the other stuff I could get--the Teflon(r) being replaceable with oil paper??? Any help would be greatly appreciated. N.B: I am Not trying to infringe on a patent, just trying to make some "homebrew" air electrodes for R&D since I am
still (steam comes out of ears) self-funded and low on funding...lol. Thanks a lot!!! =)
