Research on Electrochemical Energy Conversion Systems
Abstract
The research on electrochemical energy conversion systems has involved work on two tasks: a search for electrolytes alternative to phosphoric acid for direct and indirect hydrocarbon-air fuel cells, and a study of the corrosion characteristics of electrolytes for intermediate-temperature hydrocarbon-air fuel cells. The anodic oxidation of propane and the reduction of oxygen (air) were studied in trifluoromethanesulfonic acid monohydrate. Three techniques were used, the galvanostatic pulse technique, the potential ramp technique, and cyclic voltammetry. All three techniques indicate that the enhanced electrode activity of propane in this electrolyte involves a mechanism different from that operating in phosphoric acid and apparently this reaction sequence does not involve certain undesirable intermediates. Preliminary corrosion tests of Steel 304, Incoloy 825, Hastelloy C, Carpenter 20 indicate that the Cf3SO3H.H2O electrolyte is substantially less corrosive than phosphoric acid.
