The oxidation and resultant degradation of metal electrodes in electrochemical cells is substantially reduced and/or suppressed by the presence of a conductive organic polymeric layer on the metal electrode. For example, a platinum electrode coated with a film of pyrrole black polymer about 100 angstroms thick increases the platinum oxidation resistance fifteen fold.
