Molten carbonate fuel cell technology improvement. [25 kW]
This report summarizes the work performed under Department of Energy Contract AC21-87MC23270 during the period March 1, through May 30, 1990. The overall objective of this program is to define a competitive CG/MCFC power plant and the associated technology development requirements and to develop an improved cell configuration for molten carbonate fuel cells which has improved performance, has reduced cell creep and electrolyte management consistent with 40,000 hour projected life, reduces existing cell cost, and is adaptable to a range of power plant applications. The 8-ft{sup 2} 20-cell, 25-kW stack assembly and installation in the test facility were completed. Testing of the stack was started and 896 hours of test time were reached. Manifold seal development focused on a seal to reduce electrolyte transport and test rigs were initiated for shunt current and seal leakage evaluation. Development on sheet metal parts was initiated with focus on improved aluminization for separator plate corrosion protection and nickel clad stainless steel for the anode current collector. Development of porous parts was initiated with focus on an alternative binder for the electrodes. Design of a laboratory scale continuous debinding oven was completed. Development of an improved material blend for the matrix was also initiated. 19 figs., 2 tabs.
