Evaluation of Phosphoric Acid Matrix Fuel Cells

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 Pt/sq cm (supported on carbon) 8- 10 watts/sq 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.
