Non-Wetting Materials for Fabrication of Fuel Cell Electrodes.
Abstract
A study of propane electrooxidation on a platinum coated ion exchange membrane was conducted in both 85% phosphoric acid and trifluoromethanesulfonic acid monohydrate (TFMSA). The phosphoric acid system's propane electrooxidation currents were characterized with respect to temperature, propane flow rate and oxidation potential. Then, the propane electrooxidatin currents of the TFMSA system were determined and compared to the phosphoric acid system. The steady state currents in the TFMSA solvent were two times greater than in the 85% H3PO4 acid solvent. Steady state hydrogen electrooxidation current measurements were made in both solvents and compared to the propane electrooxidation currents to estimate the practicability of propane electrooxidation. On a mole basis, the propane currents were 1/143 of the hydrogen currents. (Author)
