ABSTRACT:
A cathode for use in a hydrazine/air fuel cell which comprises a sintered nickel substrate having a silver electrocatalyst deposited thereon and having, on one side, a semipermeable hydrophobic membrane, and on the other side thereof a hydrophilic microporous separator membrane. The silver-sintered nickel substrate may be wet-proofed by dipping in a solution of PTFE and in order to lower polarization of the cathode the silver-sintered nickel substrate may be amalgamated by treatment with a mercuric salt.
