Abstract An important advantage of anion-exchange membrane fuel cells (AEMFCs) is non-noble metal catalyst (NMCs) can be used in cathode thus drastically reducing the cost compared to proton exchange membrane fuel cells (PEMFCs). However, development of ionomer binder and membrane in perfluorinated membrane electrode assembly (MEA) for NMCs-based cathode are still insufficient. Here, we created a perfluorinated MEA containing metal-free-catalyst cathode derived from soluble perfluorinated ionomer and its membrane via catalyst-ink-based methods. Meanwhile, metal-free nitrogen-carbon (N, S-P-CNFs) electrocatalyst structure with soluble ionomer as the catalyst blinder was prepared and exhibits obviously 4e ORR catalysts activities. The resulting perfluorinated MEA exhibits a peak power density of 105.1 mW cm-2 at 80°C (Pt/C cathode and N, S-P-CNFs anode) in H2/O2 (CO2-free) fuel cells.

用于阴离子交换膜燃料电池的含无金属催化剂阴极的全氟化膜电极组件

摘要 阴离子交换膜燃料电池（AEMFCs）的一个重要优点是阴极可以使用非贵金属催化剂（NMCs），从而与质子交换膜燃料电池（PEMFCs）相比大大降低了成本。然而，用于NMCs基阴极的全氟化膜电极组件（MEA）中离聚物粘合剂和膜的开发仍然不足。在这里，我们通过基于催化剂墨水的方法创建了一种包含无金属催化剂阴极的全氟化 MEA，该阴极源自可溶性全氟化离聚物及其膜。同时，制备了以可溶性离聚物为催化剂遮蔽物的无金属氮碳（N，SP-CNFs）电催化剂结构，并表现出明显的4e ORR催化剂活性。所得全氟化 MEA 在 80°C 下的峰值功率密度为 105.1 mW cm-2（Pt/C 阴极和 N，
