✦ Synopsis

The rates of anodic oxidation of H, in acid electrolyte on WC and on the isostructural ternary alloy Mel -,W,C, with MO occupying 70-80"/, of the metal sites, have been compared experimentally.

The ternarv catalvzes the reaction as effectivelv aa WC. bv the same mechanism. and is eauallv tolerant of CO entrained in <he H, feed. Evidence is presented which indicates that proton discharge is-rateiimiting on these carbides, and that their performance is limited by scarcity of active sites and hence open to improvement by appropriate preparative technique.
