Aqueous Trifluoromethane Sulfonic Acid Fuel Cells.

Abstract

Hydrogen-air fuel cells were successfully operated with 6M TFMSA as the electrolyte at temperatures as high as 90 C. The fuel cell performance was enhanced over similarly loaded electrodes in H3PO4 due to the apparent improved kinetics for the oxygen reduction reaction. A variety of unsupported and supported Pt electrocatalysts could be effectively utilized. Subscale TFMSA fuel cells could be operated stably for periods as long as 3000 hours. Evaluation of TFMSA electrolytes in stack configurations was encouraging as acceptable initial performance levels were demonstrated. (Author)
