A fuel cell contains an electrolyte layer composed of an anion-exchange membrane, and a fuel-side electrode and an oxygen-side electrode arranged opposite to each other with the electrolyte layer between them. The fuel-side electrode contains cobalt as a metal catalyst. A compound containing at least hydrogen and nitrogen such as hydrazine is used as the fuel.

ANODE FOR LIQUID FUEL CELL
An anode suitable for use in a liquid fuel cell consists of 0.5-40.0 wt% metallic cobalt supported on a finely divided electrically conductive carrier eg carbon, and an oxidation catalyst. The anode may also contain up to about 40 % by weight of at least one additional metal. The oxidation catalyst is made by the addition of about a 3-fold stoichiometric excess of a reducing agent to an aqueous solution of a cobalt(II) compound in the presence of the carbon.

FUEL CELL CATALYST
A supported catalyst comprises microstructured support whiskers bearing nanoscopic catalyst particles, produced by a) vacuum deposition of material from a first carbon target in the presence of nitrogen and b) of vacuum deposition of material from a second target comprising at least one transition metal, ie iron or cobalt the second target comprising no precious metals.
