... performance is better for an open ratio of 75% as compared to ratios of 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current densities, and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells...

... or hydrophilic were seldom discussed in previous research. Therefore, this paper focuses on the electrode of the anode. The anodic gas diffusion layer (GDL) is treated with different hydrophilic degrees. Then, the microstructure of GDL is examined using SEM. The water content and water droplet contact angle...

...Yves Deyrail; Frej Mighri; Serge Kaliaguine The aim of this work is to improve the porosity of gas diffusion layers (GDLs) for proton exchange membrane fuel cell electrodes. These GDLs are made by twin-screw extrusion process from conductive formulations composed of polyamide11 (PA11)/polystyrene...
