The improvement of proton exchange membrane fuel cell(PEMFC)performance depends on the ability of mass transfer.Based on the theoretical analysis,the investigation focusing on the enhancement of mass transfer has been carried out using three dimension model through two methods,adding blocks in gas channel and perforation of gas diffusion layer(GDL).The results show that the two methods above would effectively strengthen the ability of mass transfer and improve the performance of the PEMFC.What's more,extra ...
