    摘要: A method is disclosed for preparing a dimensionally stable electrode structure, particularly nickel-chromium anodes, for use in a molten carbonate fuel cell stack. A low-chromium to nickel alloy is provided and oxidized in a mildly oxidizing gas of sufficient oxidation potential to oxidize chromium in the alloy structure. Typically, a steam/H.sub.2 gas mixture in a ratio of about 100/1 and at a temperature below 800.degree. C. is used as the oxidizing medium. This method permits the use of less than 5 weight percent chromium in nickel alloy electrodes while obtaining good resistance to creep in the electrodes of a fuel cell stack.

    摘要: 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.
