Fuel cell catalyst, manufacturing method thereof, and membrane-electrode assembly containing the same

摘要

Disclosed are a fuel cell catalyst that is excellent in both performance and durability, a method for producing the same, and a membrane-electrode assembly containing the same. The fuel cell catalyst of the present invention comprises a support; and a transition metal-doped or transition metal-partially alloyed surface modified with at least one transition metal selected from the group consisting of Mo and Mo, or a transition comprising said transition metal It includes a transition metal-doped or transition metal-partially alloyed internal region.
