Abstract:

Air breathing matrix type phosphoric acid fuel cells are evaluated with propane and cracked methanol fuel. Cell operation with cracked methanol appears feasible at about 150 C. With propane, higher operating temperatures are required. At 200 C with anode loadings of 3 mg Ptsq cm supported on carbon 8- 10 wattssq ft are attained initially. Performance, however, decays to 5 watts sq ft or less in a period of several hundred hours. Initially, fuel utilization in excess of 70 is obtained.
