[Also in Division C7] An electrode, for use as an anode in a fuel cell, comprises a porous metal layer formed from Ni, Co, Fe or Cu with Al, Si or Zn which is subsequently dissolved out, and an electroless or electrolytic coating of an alloy consisting of 90 to 70% Pd and 10 to 30% Ru. The porous layer may be formed on a conductive support of, e.g., graphite, carbon, Ni (as a grid or sheet) or steel, by either electrolysis, vapour deposition, flame-spraying or dipping the support in an adhesive and then coating with metal powder. The porous coating may be heated to 300‹ to 700‹ C. in nitrogen. A fuel cell consists of the electrode used as an anode 29, closure plates 24, 25, nickel grids 26, 27 as spacers, and a cathode 28 separated from the anode 29 by a diaphragm 30. |
