Research on electrochemical energy conversion systems. Interim progress report No. 6, April--October 1974. [Trifluoromethanesulfonic acid monohydrate electrolyte]
Technical Report

OSTI ID:7237488
The research 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 effort during this reporting period has been concentrated on the further investigation of the electrochemical behavior of trifluoromethanesulfonic acid monohydrate as a fuel cell electrolyte. The studies dealt with the use of methanol as a fuel, both from electrooxidation at a platinum electrode and from its tendency to interfere with the air electrode. Methanol dissolved in CF/sub 3/SO/sub 3/H . H/sub 2/O was electrooxidized over a temperature range of 23C to 135C with the highest rate in the neighborhood of 80C. At temperatures above 100C vaporization losses are excessive. Methanol interferes with the air electrode. The electrochemical activities of hydrogen, propane, and air were investigated at a platinum electrode in CF/sub 3/SO/sub 3/H . H/sub 2/O at 23C.
