GAS DIFFUSION LAYER MEMBER FOR SOLID POLYMER FUEL CELLS, AND SOLID POLYMER FUEL CELL

摘要

Provided is a gas diffusion layer member with a good relative humidity (RH) balance. The gas diffusion layer member for solid polymer fuel cells comprises a sheet-form gas-permeable conductive base material with a thickness within the range of 100 to 250µm, wherein the moisture permeability is within the range of 1300 to 2000g/m2/h as measured in accordance with JIS L 1099:2006.
