CATALYST FOR CATHOD OF MIXED REACTANT FUEL CELL, AND MEMBRANE-ELECTRODE ASSEMBLY FOR MIXED REACTANT FUEL CELL AND MIXED REACTANT FUEL CELL SYSTEM INCLUDING SAME

摘要

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 chalcogenide 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 chalcogenide selected from the group consisting of S, Se, Te, and combinations thereof. The cathode catalyst can improve power characteristics of a fuel cell due to excellent catalyst activity and selectivity.
