Abstract

The significant use of platinum for catalyzing the cathodic oxygen reduction reactions (ORRs) has hampered the widespread use of polymer electrolyte membrane fuel cells (PEMFCs). The construction of well-defined electrode architecture in nanoscale with enhanced utilization and catalytic performance of Pt might be a promising approach to address such barrier. Inspired by the highly efficient catalytic processes in enzymes with active centers embedded in charge transport pathways, here we demonstrate for the first time a design that allocates platinum nanoparticles (Pt NPs) at the boundaries with dual-functions of conducting both electrons by aid of polypyrrole and protons via Nafion(®) ionomer within hierarchical nanoarrays. By mimicking enzymes functionally, an impressive ORR activity and stability is achieved. Using this brand new electrode architecture as the cathode and the anode of a PEMFC, a high mass specific power density of 5.23 W mg(-1)Pt is achieved, with remarkable durability. These improvements are ascribed to not only the electron decoration and the anchoring effects from the Nafion(®) ionomer decorated PPy substrate to the supported Pt NPs, but also the fast charge and mass transport facilitated by the electron and proton pathways within the electrode architecture.

摘要

铂在催化阴极氧还原反应（ORR）中的大量使用阻碍了聚合物电解质膜燃料电池（PEMFC）的广泛应用。构建具有增强的铂利用率和催化性能的纳米级明确电极结构可能是解决这一障碍的一种有前途的方法。受活性中心嵌入电荷传输途径的酶中高效催化过程的启发，我们首次展示了一种设计，即在分层纳米阵列中借助聚吡咯传导电子以及通过Nafion®离聚物传导质子的双重功能，将铂纳米颗粒（Pt NPs）分配在边界处。通过功能上模拟酶，实现了令人印象深刻的ORR活性和稳定性。使用这种全新的电极结构作为PEMFC的阴极和阳极，实现了5.23 W mg(-1)Pt的高质量比功率密度，并且具有出色的耐久性。这些改进不仅归因于Nafion®离聚物修饰的聚吡咯底物对负载的Pt NPs的电子修饰和锚固作用，还归因于电极结构内电子和质子途径促进的快速电荷和质量传输。
