Abstract

An in situ test method has been developed to study the Co(OH)2-PPy-BP cathode status during DBFC operation. It is found that some Co(2+) ions are oxidized to Co(3+) present in CoOOH during cell operation. A mechanism for the oxygen reduction reaction on the Co(OH)2-PPy-BP cathode in alkaline media has been proposed.
