Research on Electrochemical Energy Conversion Systems.
Abstract
The research on electrochemical energy conversion systems has involved a search for electrolytes alternative to phosphoric acid for direct and indirect hydrocarbon-air fuel cells. It has concentrated on trifluoromethanesulfonic acid monohydrate and perfluorobutyric acid. Experiments in which hydrogen was electrooxidized showed that the enhanced performance of the sulfonic acid is not restricted to propane. Further, it is indicated that adsorption intermediates of the type seen in phosphoric acid and detrimental to the efficiency of the process are absent in this electrolyte. The electro oxidation of propane in perfluorobutyric acid proceeds at a lower rate than in CF3SO3H.H2. An apparatus and technique to measure the solubility of gases in electrolytes was installed. Preliminary measurements of the solubility of propane in CF3SO3H.H2O are in the same range as those reported for H3PO4. (Modified author abstract)
