abstract |
The invention relates to a platinum alloy catalystnon an electrically conductive carbon support, whichnan alloy of 40 to 60 atom% platinum, 10 to 20 atom%nRhodium and 20 to 50 atomic% iron in the form of fine particlesnContains alloy particles. This is the catalystncharacterized in that the average particle size of thenAlloy particles is less than 10 nm. |
