摘要: The invention refers to a fuel cell electrode for oxidation preferably methanol or reformate in with acid electrolytes. material comprises of a) carbons modified by the chemisorption covalent attachment metallocomplexes, over which noble metal catalyst such as platinum is deposited, b) carbon-noble systems mixed and c) mixtures blacks metallocomplexes. An improvement 100-200 mV seen controls using alone full tests oxygen air. advantages disclosed promoters use low loaded (20% Pt on carbon) electrodes rather than pure alloy blacks.
