Abstract:
Improved oxygen reduction reaction catalysts include octahedral nanoparticles of a platinum-copper-nickel alloy contacted by a secondary ionomer. The alloy can have a formula of Pt 2 CuNi, and the secondary ionomer can include an ionic liquid, 1-methyl-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,2-a]pyrimidin-9-ium 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonate ([MTBD][C 4 F 9 SO 3 ]). The oxygen reductions catalysts have improved stability, as well as mass area and specific area comparted to competing catalysts.

Claim (Index 19):
The cathode as recited in  claim 13 , wherein the secondary ionomer is present at a weight ratio relative to the platinum alloy within a range of 2.5:1 to 2.6:1.
