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.
