ABSTRACT:
A fuel cell anode for the oxidation of methanol, which contains at least one platinum metal or alloys of platinum metals as the primary, catalytically active component. The anode is characterized in that it also contains transition metal complexes of phthalocyanine or substituted phthalocyanines as cocatalyst, these amplifying the catalytic effect of the platinum metals and their alloys for the anodic oxidation of methanol.
