Over 750 hours and five thermal cycles with performance close to the E-line goal have been accumulated on the second 10-ft/sup 2/ short stack at 120 psia and 405/sup 0/F. A subscale cell cut from 10-ft/sup 2/ electrodes in the same batch used for the second 10-ft/sup 2/ short stack has accumulated over 2800 hours with performance above the E-line goal at 120 psia and 400/sup 0/F. Over 12,700 hours and 36 thermal cycles have been accumulated on the 3.7-ft/sup 2/, 30-cell short stack at 120 psia and 405/sup 0/F. Successful operation of automatic off-loading apparatus was demonstrated in conjunction with the substrate forming machine. Approximately 500 10-ft/sup 2/ separator plates were molded. Feasibility for significant reduction in cooler processing time was demonstrated by the bonding of multiple subassemblies in the same cycle. Testing was completed on the first three builds of the 7-cell, cross pressure tolerance stack. 28 figs., 7 tabs.
