The mass transfer characteristics of gas diffusion layer (GDL) are closely related to cell performance in PEFC. In this study, following simultaneous measuring method was tried out, namely, the oxygen diffusivity of porous media with moisture was measured by using an experimental apparatus consist of oxygen sensor based on galvanic battery, and liquid water distribution in porous medium was visualized by using Neutron Radiography. It was confirmed that the method was effective in analyzing relationship between liquid water distribution and oxygen diffusivity. The relationship has been studied for hybrid type porous media.
