Exploration of the oxygen transport behavior in non-precious metal catalyst-based cathode catalyst layerfor proton exchange membrane fuel cells

Shiqu CHEN, Silei XIANG, Zehao TAN, Huiyuan LI, Xiaohui YAN, Jiewei YIN, Shuiyun SHEN, Junliang ZHANG

Frontiers in Energy 2023, Volume 17, Issue 1,   Pages 123-133 doi: 10.1007/s11708-022-0849-1

Abstract: High cost has undoubtedly become the biggest obstacle to the commercialization of proton exchange membraneon NPMC-based fuel cells focus on developing highly active catalysts rather than facilitating oxygen transportUsing Zn-N-C based DCLs of different thickness, the bulk oxygen transport resistance at the unit thicknessResults show that the ratios of local and bulk oxygen transport resistances in NPMC-based CCL are 80%and 20%, respectively, and that an enhancement of local oxygen transport is critical to greatly improve
