Abstract
Electrode material composed of metal encapsulated substrate particles for making into an electrode for a molten carbonate fuel cell is produced by electroless plating of a metal electrochemically active for the reactions of the cell onto a substrate particle which is non-sintering at the operating temperatures of the cell.
Claims4
An electrode useful for a molten carbonate fuel cell consisting of metal encapsulated substrate particles sintered together only by means of said metal without significant exposure of the surface of said substrate particles, said electrode having a pore volume greater than 40% by volume but less than 85% by volume of the electrode, said electrode having a pore size ranging from about 0.1 micron to about 20 microns, said metal being selected from the group consisting of copper and nickel, and said substrate particles being selected from the group consisting of lithium aluminate, strontium titanate, .alpha.-alumina and mixtures thereof, said substrate particles ranging in size from about 0.1 micron to about 100 microns.
