A direct methanol fuel cell (DMFC) having a methanol fuel supply, oxidant supply,
and its membrane electrode assembly (MEA) formed of an anode electrode and a cathode
electrode with a membrane therebetween, a methanol oxidation catalyst adjacent
the anode electrode and the membrane, an oxidant reduction catalyst adjacent the
cathode electrode and the membrane, comprises an oxidant reduction catalyst layer
of a platinum-chromium alloy so that oxidation at the cathode of methanol that
crosses from the anode through the membrane to the cathode is reduced with a concomitant
increase of net electrical potential at the cathode electrode.
