• H123 Effect of Microstructure of Cathode MPL on Liquid Water Transport and Performance Characteristics in PEFC

抄録

Microporous layer (MPL) has a dramatic effect on water management in polymer electrolyte fuel cells (PEFCs), because its microstructure reduces liquid water accumulation at cathode CL/GDL interface. In this paper, the microstructure of MPLs fabricated from different carbon black (CB) loadings was observed using scanning electron microscope (SEM). Furthermore, the effect of CB loading of MPL on the liquid water transport and performance characteristics in a PEFC was experimentally investigated. It was found that several particle agglomerates are formed in the MPL with high CB loading of 4.0 mg/cm^2, and effective in alleviating water flooding in the cathode electrode.
