HYDROCARBON-AIR FUEL CELLS
Abstract
Detailed information is presented on a continuing research and development program to develop a direct hydrocarbon oxidation-air fuel cell technology. Current work included research on electrochemical oxidation processes, electrocatalysts, electrolytes, electrode structure, fuel cell life testing, and studies of selfsustaining operation. Multi-pulse potentiodynamic techniques were further developed for analyzing hydrocarbon surface processes. Performance of fuel cell systems with hydrogen fluoride and cesium fluoride electrolytes were studied for high performance hydrocarbon oxidation. Boron carbide was successfully employed as a substrate for high surface area platinum, and the results and application to Teflon bonded electrodes are reported. A variety of modified Teflonbonded developmental electrodes were evaluated including the initial results of asbestos reinforced Teflon. Performance and electrode life in excess of 3000 hours on best electrodes are reported for a variety of hydrocarbon fuels. Studies to define the requirements for self- sustaining operation are also included.
