Abstract

Gas diffusion layer (GDL) is a crucial component of a proton-exchange membrane fuel cell (PEMFC) that participates in the transport of reactant gases and removes water from the system. In this research, a two dimensional (2D) model was developed and simulated to determine the effects of porosity and thickness of GDL on PEMFC performance by using MATLAB. The GDL model presented the contour profiles illustrating the distribution of oxygen mass fraction in the cathode GDL. The model also well agreed with experimental results available in literature. In the simulation of GDL model, higher-porosity GDL showed higher cell performance because of the numerous void spaces that enhanced the diffusion of oxygen to the catalyst layer. Simulation results further showed that a thicker GDL produced a lower-performance cell fuel. All these factors contributed to the lower oxygen concentration near the catalyst layer and GDL interface and thus the lower cell performance. Through the GDL model, the optimum porosity and thickness of GDL were found to be 0.8 and 130 μm, respectively.
