OSTI ID:6273784

Significant progress has been made in the areas of internal reforming cell testing, creep resistant anode development and NiO solubility suppression. 4000 hours of fuel cell operation on direct methane feed has been achieved with Cell 7-53 which contains a MgO/Ni reforming catalyst in the anode chamber. No decay in methane reforming or fuel cell performance has been observed to-date. No reduction in anode thickness was realized with a Ni-Al alloy anode which operated in a cell test for 1200 hours at 650/sup 0/C with 25 psi cell clamping pressure. A four to five fold reduction in NiO solubility has been demonstrated in out-of-cell tests by adjusting parameters to favor a more basic carbonate melt. Favorable conditions for reduced NiO solubility include high lithium melt compositions and low water and carbon dioxide partial pressures. Component development is concentrating on two primary activities: development of a creep resistant ribbed anode and development of an internal reforming catalyst for methane reforming in the MCFC anode environment. 15 figs., 17 tabs.
