- The above is quite untrue. Scientific american in the late 70s (I think)
- had at least two articles in their Am. Scientist section, on home made
- fuel cells. One was an Oxy Hydrogen cell. One electrode as I recall was a
- porous carbon electrode activated with silver. The carbon came from a dry
- cell center electrode. The other electrode may have been nickel mesh,
- The other cell burned eiterh methanol or ethanol, and had a gelled
- electrolyte I think. The electrodes were nickel mesh, one of which had a
- small ammount of palladium catalyst. Neither of these was high power,
- but both would be suitable for science fairs.
