EVALUATION OF PHOSPHORIC ACID MATRIX FUEL CELLS.
Abstract
An evaluation of air breathing phosphoric acid matrix fuel cell units is carried out. Cells are life tested with synthetic steam reformate at about 150C. Initially, 70 watts/sq ft is obtained at .75 volts and 90 watts/sq ft at .70 volts using a platinum loading on anode and cathode combined of 12.5 mg/sq cm. Cell decay rates vary widely and appear to be closely related to the nature of the matrix material. With suitable matrices decay rates at a current density of 100 Amp./sq ft are below 5 millivolts/100 hours. The primary direct cause of cell decay is recrystallization of the cathode catalyst.
