Fuel Cell Electrolyte for Portable Electrical Generating Equipment.

Abstract

The goal of the research program was to synthesize and test a substitute electrolyte for phosphoric acid in primary fuel cells with the necessary physical, chemical and electrochemical stability to operate from room temperature to 150 C. This goal was successfully met and exceeded with a perfluorinated acid (hexafluorobutane tetrasulfonic) produced which operates over the temperature range of at least OC to 150C in hydrogen-oxygen fuel cells. In addition, ECO prepared and tested a second perfluorinated acid (hexafluoro-2, 3- butene disulfonic acid) which appears to have similar properties. The use of these new electrolytes in primary fuel cells is expected to significantly reduce start-up time, extend operational temperature range, and to minimize problems related to CO-poisoned fuels.
