Technology development for materials, cell components, and reformers for on-site integrated energy systems is described in the Final Report. Significant progress includes: (1) heat-treatment of 25 cm/sup 2/, 350 cm/sup 2/, and 1200 cm/sup 2/ cell test hardware has been accomplished; (2) electrochemical and chemical corrosion rates of heat-treated and as-molded graphite phenolic resin composites in phosphoric acid were determined; (3) three cell, 5 in. x 15 in. stacks have operated for up to 10,000 hours and 12 in. x 17 in. five cell stacks were tested for 5000 hours; (4) a three cell 5 in. x 15 in. stack with 0.12 mg Pt/cm/sup 2/ anodes and 0.25 mg Pt/cm/sup 2/ cathodes was operated for 4500 hours; and (5) an ERC proprietary high bubble pressure matrix, MAT-1, was tested for up to 10,000 hours.
