Abstract
Molten carbonate fuel cell cathodes formed from a composition comprising oxides of nickel, lithium salts and barium salts having improved strength. These cathodes are fabricated by prefiring oxides of nickel and optionally lithium salts. The prefired powder is optionally leached with an organic acid and optional barium salts may be added. These powders are formed into an electrode and sintered. The resulting electrodes have improved strength.
