Abstract
Cost reduction is the key challenge for commercialization of fuel cell vehicles, and reduction of Platinum amount in catalyst layer without sacrificing performance is essential. To understand the effect of Platinum loading on the transport phenomena within the cathode catalyst layer, performance test and cyclic voltammetry were carried out. Results suggested that local transport loss within the cathode catalyst layer was not fully captured with a normalized Platinum surface area. Furthermore, effect of Platinum loading on nanoscopic structure of the catalyst layer, and more detailed investigation is required to understand the phenomena within the cathode catalyst layer.
