Au stabilization effect on Pt catalysts for oxygen reduction reaction
Abstract
Hydrogen-fueled proton-exchange membrane fuel cells (PEMFCs) are promising renewable energy due to the only by-product is water and low operating temperature [1]. In the last decades, It has been proved that platinum is the most efficient catalyst for oxygen reduction reaction in the application of PEMFCs [2]. However, the less abundance and high cost of Pt hampers the commercialization of fuel cell technology. Therefore, it is important to increase the activity, stability and utilization efficiency of Pt catalyst.
