G0801-2-4 Heat and Mass Transport Characteristics of Gas Diffusion Layer

Abstract

The heat and mass transport characteristics of gas diffusion layer have strong influence on Polymer Electrolyte Fuel Cell (PEFC) performance. In this study, we measured thermal conductivity of GDL by steady state method and discussed about diffusive characteristics of GDL. Little difference was observed in diffusive resistances of GDL with or without PTFE. Measured diffusive resistances can be organized by (u/l)^<0.5>
