Over 550 hours and four thermal cycles with performance close to the E-line goal have been accumulated on the second 10-ft/sup 2/ 28-cell stack at 120 psia and 405/sup 0/F. Over 12,400 hours and 35 thermal cycles have been accumulated on the 3.7-ft/sup 2/ 30-cell 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/, 28-cell stack has accumulated over 2200 hours with performance close to E-line at 120 psia and 400/sup 0/F. Testing was completed on the first three builds of the 7-cell, crosspressure tolerance stack.
