Development of molten carbonate fuel cell power plant technology. Quarterly technical progress report No. 18, January 1-March 31, 1984
This report summarizes the work performed to develop and verify the design of a prototype molten carbonate fuel cell stack which meets the requirements of a 1990's-competitive, coal-fired, electrical utility central station, or industrial cogeneration power plant. Fabrication of the cell components to be used in the 100-cell stack was completed successfully. Compressive creep of the anode to be used in the 100-cell stack was measured through 720 hours of testing at 1300/sup 0/F. The data continue to support the creep resistance of this component. Anode and bubble barrier pore spectra data obtained after aging at 1300/sup 0/F confirmed the sintering resistance of these components. A parametric study of candidate separator material data obtained from retort corrosion tests was completed. Based on the study, cell testing of treated INCO 825 was begun. A 1000 hour cell test of Ni-201/316SS at accelerated test conditions showed no failure of this separator plate material. Single cell tests to evaluate Co-based and Ti-based alternate cathode materials were conducted. The cell test performance data and post test chemical analysis show both materials are unstable. Cell testing of a doped Fe-based cathode showed a reaction with the matrix used. A repeat test using a different matrix material is planned. Testing of the 20-cell Subscale Stack was completed on schedule following 2000 hours of operation. A post test analysis was begun in order to correlate the diagnostic test data with the physical evidence of component stability, including electrolyte containment. 29 figs., 35 tabs.
