Abstract Efficiency of a Direct methanol fuel cells (DMFCs) not just merely depends on the catalyst, but also on the flow channels, physical/electrochemical kinetics, Membrane Electrode Assembly (MEA) preparation and other operating parameters. This article is focused on the influence of novel flow field design and the effect of Nafion loading during MEA preparation on the performance of DMFC. A novel Pt/NiTiO3 was used as the anode electrocatalyst in the DMFC. The results show a 27.8% & 5.1% increment in cell performance due to changes in Nafion loading and flow field designs, respectively. A Nafion loading of 0.5 mg/cm2 and the sinuous flow field gave the highest performance. Thus, Pt-NiTiO3/C performed to be an encouraging anode catalyst with the new sinuous flow field.

Nafion 负载和新型流场设计对提高 DMFC 性能的创新阳极电催化剂的影响

摘要 直接甲醇燃料电池 (DMFC) 的效率不仅取决于催化剂，还取决于流动通道、物理/电化学动力学、膜电极组件 (MEA) 制备和其他操作参数。本文重点介绍新型流场设计的影响以及 MEA 制备过程中 Nafion 负载对 DMFC 性能的影响。新型 Pt/NiTiO3 用作 DMFC 中的阳极电催化剂。结果显示，由于 Nafion 负载和流场设计的变化，电池性能分别增加了 27.8% 和 5.1%。0.5 mg/cm2 的 Nafion 负载和蜿蜒流场提供了最高的性能。因此，Pt-NiTiO3/C 在新的蜿蜒流场中表现出令人鼓舞的阳极催化剂。
