Influence of Anisotropic Transport Properties of the GDL on the Performance of PEMFCs

A two-dimensional, non-isothermal two-phase model, which includes the full anisotropy of GDL, was developed to investigate the effect of anisotropic ratios on cell performance. Among the four anisotropic ratios, the anisotropic ratio of diffusivity,γD, is the most sensitive parameter to cell perform...

Description
Summary:A two-dimensional, non-isothermal two-phase model, which includes the full anisotropy of GDL, was developed to investigate the effect of anisotropic ratios on cell performance. Among the four anisotropic ratios, the anisotropic ratio of diffusivity,γD, is the most sensitive parameter to cell performance. The present study demonstrated the possibility of improving cell performance by using innovated GDL porous materials with higher anisotropic ratios, especially higher γD
