Component development concentrated on two objectives: development of a creep resistance ribbed anode and development of an internal reforming catalyst for steam-methane reforming in the MCFC anode. Satisfactory anode creep strength has been achieved with Ni + 16 wt % LiAlO composite anodes. Efforts concentrated on fabrication methods to directly produce a ribbed anode from the Ni + LiAlO/sub 2/ powder mixture. Encouraging results were obtained by mold compression in a machined graphite mold followed by in-mold sintering which was promoted by the use of a few percent LiKCO/sub 3/ as a sintering agent. Internal reforming catalyst development focused on preparation techniques for high surface area Ni catalyst supported on ..gamma..-LiAlO/sub 2/. The approach which is being most actively pursued involves first pelletizing the LiAlO/sub 2/ into suitable granule size followed by multiple impregnation in nickel salt solution and heat treatment. Several impregnations are necessary to obtain a nominal Ni loading of 15 wt %. Out-of-cell catalyst testing has been initiated in planar integral reactors as well as differential tube reactors. The LiAlO/sub 2/ supported catalyst granules have demonstrated high activity for the methane-steam reforming reaction and kinetic parameters compare favorably with those for commercially available reforming catalysts. Results are detailed. (WHK)
