摘要

本研究分析了创新气体扩散层(GDL)的新人工变化,以最大限度地提高质子交换膜燃料电池(PEMFC)的性能。具体来说,通过对单通道 PEMFC 进行三维建模和模拟,使用新型穿孔槽均匀气体扩散层(PG-GDL)来改善排水和氧气传输。利用 PG-GDL 内部的沟槽深度对不同的穿孔 GDL 和传统 GDL 进行了比较分析。研究结果表明,PG-GDL 中均匀的沟槽形状能产生更均匀的氧气流和分布,从而全面提高 PEMFC 的性能。我们的研究表明,应采用适当的 GDL 设计来优化 PEMFC 性能。

Enhancing oxygen distribution in proton exchange membrane fuel cells based on modified gas diffusion layer designs: a comparative study

Enhancing oxygen distribution in proton exchange membrane fuel cells based on modified gas diffusion layer designs: a comparative study

This study analyzes new artificial changes in innovative gas diffusion layers (GDLs) to maximize the performance of proton exchange membrane fuel cells (PEMFCs). Specifically, a new perforated grooved uniform gas diffusion layer (PG-GDL) is used to improve the water drainage and oxygen transport using three-dimensional modeling and simulations of a single-channel PEMFC. Comparative analyses are performed between the different perforated GDLs and the conventional GDLs using groove depth inside a PG-GDL. Findings show that the uniform grooved shape in the PG-GDL produces a more uniform oxygen flow and distribution with an overall improvement in the PEMFC performance. Our study shows that the appropriate GDL design should be obtained to optimize the PEMFC performance.

期刊介绍: Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
