By the analysis of physical and electrochemical test results, it is found that the performance of GDL prepared by composite carbon black is obviously improved compared with conventional GDL prepared by single carbon black. This new GDL combines the characteristics of two original carbon materials and has a more reasonable pore structure, which can meet the good transmission of reaction gas and liquid water. Furthermore, the research shows that the pore size distribution of GDL can be effectively adjusted by changing the proportion of composite carbon black. The GDL with composite carbon black consisting of 70 wt.% Acetylene Black carbon and 30 wt.% Vulcan XC-72 is finally confirmed to have the best fuel cell performance. CONFLICT OF INTEREST None.
