چکیده
Abstract An advanced cathode design can improve the power performance and durability of proton exchange membrane fuel cells (PEMFCs), thus reducing stack cost cell vehicles (FCVs). Recent studies on highly active Pt alloy catalysts, short-side-chain polyfluorinated sulfonic acid (PFSA) ionomer 3D-ordered electrodes have imparted PEMFCs with boosted density. To achieve compacted target 6 kW/L or above for wide commercialization FCVs, developing available cathodes high-power-density operation is critical PEMFC. However, current developments still remain extremely challenging respect to stable catalysts in practical operation, controlled distribution catalyst surface poisoning oxygen penetration losses 3D (three-dimensional)-ordered layers low Knudsen diffusion molecular. This review paper focuses impacts development automotive systems concludes directions provide greatest benefit.

The produced liquid water in cathode catalyst layer (CCL) has significant effect on the operation of proton exchange membrane fuel cell (PEMFC). To investigate this effect, the transport of oxygen in CCL in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. The CCL was reconstructed as an agglomerated system. To explore the wettability effects, diffe...
