Abstract

An electrode for reducing oxygen has a substrate of low-ash carbon, such as coconut shells converted to charcoal. The substrate is loaded with a catalyst such as (i) platinum phtalocyanine or (ii) lead-ruthenium oxide. In case (ii), to make the electrode, lead ions are adsorbed onto the substrate, which is then treated with a solution of ruthenium (VI) oxide, to precipitate the catalyst on the substrate.
