New Materials for Fluorosulfonic Acid Electrolyte Fuel Cells.

Abstract

Hydrogen-air fuel cells were evaluated with both TFMSA (Trifluoromethane sulfonic acid) monohydrate and dilute TFMSA. Tolerance against flooding was increased by use of thick supported catalyst electrodes with the monohydrate. Fuel cells with 63% TFMSA were operated at room temperature for over 1,000 hours with no significant decay. The evaluation of supported platinum and tungsten carbide anode catalysts with dilute TFMSA was initiated. Silicon carbide was investigated as a matrix material with TFMSA. (Author)
