Abstract

Carbon electrodes have been used as cathodes in alkaline air fuel cells with some success [1-3]. The material is reasonably durable though forms that yield significant concentrations of hydrogen peroxide are slowly degraded. However, the activity of carbon can be enhanced onsiderably by impregnation with a suitable catalyst. The most ffective of these catalysts to date have proved to be noble metals uch as platinum, and 7-15 wt % platinum is commonly sed.This is a very costly route, and macrocyclic ransition-metal derivatives have also been explored as less expensive alternatives [4, 5], either as films on metallic substrates or impregnated on various forms of carbon.
