Abstract

One way to increase performance of cathode catalysts for polymer electrolyte membrane fuel cells is utilization of platinum bimetallic alloys with transition metals. These systems have demonstrated great potential to overcome the existing limitations in fuel cell technology. Being the main obstacle in fuel cell commercialization, a cathodic fuel cell reaction has motivated many research groups and developers to resolve the mechanism of catalytic enhancement for bimetallic systems. This initiated studies on well-defined surfaces that have revealed the key physicochemical parameters responsible for wide range of activities for the oxygen reduction reaction on bimetallic surfaces.
