The effectiveness of three methods of stabilizing nickel anodes in molten carbonate fuel cell (MCFC) operating environments was examined. Alloying with chromium was effective in retarding sintering at levels as low as 1 weight percent (w/o) chromium. The mechanism of stabilization, however, involved the formation of oxide films which dramatically altered electrode morphology. Dispersion of refractory oxides, e.g., Al/sub 2/O/sub 3/, was effective in stabilizing anode structures at loadings of 1 volume percent. The most promising method of stabilizing the electrode structure was found to be ''electroless'' plating of Ni and/or Cu onto refractory oxides of Al/sub 2/O/sub 3/, SrTiO/sub 3/, and LiAlO/sub 2/. This approach stabilized the structure, while providing optimum flexibility in electrode morphology design.
