The Characteristics Evaluation of the Gas Diffusion Layer for a PEM Fuel Cell by Computational Fluid Dynamics
CFD 해석을 이용한 PEMFC 용 기체확산층의 특성평가
Abstract
In this paper, a two-dimensional cross-channel model was applied to investigate influence of the gas diffusion layer(GDL) property and flow field geometry in the anode side for proton exchange membrane fuel cell(PEMFC). The GDL is made of a porous material such as carbon cloth, carbon paper, or metal wire mesh. To the simplicity, the GDL is represented as a block of material containing numerous pathways through which gaseous reactants and liquid water can pass. The purpose of present work was to study the effect of the GDL thickness and the porosity, and flow field geometry by computational fluid dynamics(CFD)
