抄録

Liquid water accumulated in the catalyst layer (CL) and gas diffusion layer (GDL) of a polymer electrolyte fuel cell (PEFC, PEMFC) results in performance deterioration due to the inhibition of oxygen transport to the cathode CL (Flooding). To enhance the drainage in the GDL, a microporous layer (MPL) employed at the CL side of the GDL substrate is effective. Hydrophilic/hydrophobic composite MPLs in-house applied have mitigated the flooding, while the mechanism was not well clarified. A pore network model (PNM) of our in-house hydrophobic MPLs is modified for the analysis of the composite MPL.
