Abstract:
The cathode catalyst for a mixed reactant fuel cell includes a mixed catalyst that includes a first catalyst including a Ru—Ch1 compound where Ch1 is a chalcogens selected from the group consisting of S, Se, Te, and combinations thereof, and a second catalyst including a Pt—Ch2 compound where Ch2 is a chalcogens selected from the group consisting of S, Se, Te, and combinations thereof. The cathode catalyst can improve excellent power characteristics of a fuel cell due to excellent catalyst activity and selectivity.
