| Research Abstract |
In this study, the liquid water accumulation at the interface between the catalyst layer (CL) and gas diffusion layer (GDL) of a polymer electrolyte fuel cell (PEFC) was quantitatively evaluated using near-infrared reflectance spectroscopy, and the effects of GDL hydrophobicity and MPL addition on the water transport at the cathode CL/GDL interface were discussed. Furthermore, the reaction distribution inside the operating fuel cell was investigated based on infrared thermographic technique.
