Electrical conductivity studies of acid doped polybenzimidazole (PBI) and 85% phosphoric acid have been carried out. The PBI contained about 600 mol-% of 85% phosphoric acid and the electrical conductivity was deduced from complex impedance studies which were made at frequencies from 10 to 10(exp 7) Hz. Measurements were made at pressures up to 0.25 GPa and temperatures of about 25, 50 and 75 deg C. Similar measurements were also ...
This report summarizes research involving mechanistic studies of the oxidation of small hydrocarbons and carbon monoxide on platinum in aqueous electrolytes, transition metal oxides as electrocatalysts for O2 reduction and as supports for dispersed platinum, and transition metal complexes exhibiting high catalytic activity for O2 reduction on graphite. This research has been pursued principally by graduate students, using the research for the Ph.D. dissertation. (Author)
