Nearly 1700 hours and 11 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 4100 hours with performance conforming close to the E-line goal at 120 psia and 400/sup 0/F. Over 14,350 hours and 39 thermal cycles have been accumulated on the 3.7-ft/sup 2/, 30-cell short stack at 120 psia and 405/sup 0/F. A subscale cell with GSB-18 catalyst completed over 10,000 hours of operation at 120 psia, 400/sup 0/F with performance within 10 mV of the E-line goal. The full-size, 10-ft/sup 2/ stack containment vessel and reactant gas manifolds were received. 17 figures, 6 tables.
