摘要: Abstract Hollow core mesoporous shell carbon (HCMSC) has been explored for the first time as an anode catalyst support in proton exchange membrane fuel cell (PEMFC). The fantastic structural characteristics of HCMSC such large specific surface area and volume well-developed three-dimensionally interconnected bimodal porosity make it excellent PEMFC. supported PtRu nanoparticles have shown smaller particle size better dispersion on than commercial black Vulcan XC-72. Considerable improvements electrocatalytic activity toward H2 oxidation performance demonstrated by HCMSC-supported compared with XC-72 ones (i.e., corresponding to enhancement more 60% power density that PtRu/Vulcan), implying is a superb
