“…The combination of fuel cell technology and hydrogen energy would definitely promote an efficient utilization of renewable energy, thus greatly alleviating problems concerning environmental pollutions and energy shortages. Polymer electrolyte membrane fuel cells (PEMFCs) possess unique advantages including high energy conversion efficiency, zero emissions, and low-operating temperature and are receiving ever-growing attention in both automotive and power plant fields. However, the high cost of PEMFCs that is mainly caused by applying a high loading of Pt-based catalysts remains a critical limitation for a large-scale commercialization of PEMFCs. It is noted that Pt loading can be continuously reduced by developing more active electrocatalysts, while the corresponding decrease in active sites leads to a severe deterioration in local mass transport resistance that results from O 2 molecules crossing the ionomer film in the cathode catalyst layer (CCL), thus lowering the cell performance under high current density. …”
