摘要

The influence of hydrophobicity and porosity of the catalyst layer (CL) and cathode microporous layer (MPLC) on water distribution and performance of polymer electrolyte membrane fuel cell (PEMFC) is investigated. Hydrophobicity of the layers is altered with the addition of PTFE (polytetrafluoroethylene) and mono-dispersed polymer particles are utilized to introduce the macro-pores with a diameter of 0.5 mu m and 30 mu m within the CL and MPLC, respectively.
