✦ Synopsis


The electrooxidation of methanol on porous carbon electrodes impregnated with bimetallic platinum group catalysts, Pt/M (M = Au, OS, Ir, Pd and Ru), in a H,SO, electrolyte is reported. Both Au and Pd are found to inhibit the reaction while Ir, OS and Ru act as promotors. The presence of metal oxides was studied by X-my photoelectron spectroscopy

(XPS) and the role of the second metal in promoting or inhibiting the methanol oxidation reaction is shown to be a result of the ease of formation of "active oxygen" groups.

High-activity platinized-carbon anodes for methanol oxidation have been prepared. XPS investigation of the electrodes showed the presence of both Pt" and oxidized Pt species. The enhanced activity of these electrodes, compared with Pt black, can be explained in terms of the unusual surface propertie

## Abstract Empirical model equations, proposed for polymer electrolyte fuel cells, are used to predict the cell voltage vs. current density response of a liquid feed direct methanol fuel cell. The model equations are validated against experimental data for a small‐scale fuel cell over a wide range
