Abstract

Flooding is one of the major issues in polymer electrolyte fuel cells (PEFCs), especially under high current density operation. Therefore, gas diffusion layers (GDLs) coated with hydrophobic microporous layers (MPLs) are usually employed to decrease water saturation at the cathode side of the cell. In this study, fluorinated carbon powders are synthesized to create superhydrophobic microporous layers to facilitate water management and prevent flooding. Fluorinated carbons are synthesized by a solvothermal method and characterized by various technics techniques. Then, either fluorinated carbon or commercially available carbon black are formed into a slurry and screen printed onto a commercial GDL to form MPLs. These MPLs are then characterized by water contact angle measurements, air permeability tests, and oxygen transport resistance measurement. Furthermore, their performance in a PEFC is evaluated using I-V measurements in a PEFC under various conditions. The results indicate that fluorinated carbon based MPLs are superhydrophobic, leading to lower oxygen transport resistance and significantly higher fuel cell efficiency compared to conventional carbon black.
