资源简介：
A microporous layer of the present invention enables obtaining a fuel cell that can be produced with high productivity and that exhibits high power generation performance and high durability. The present invention is a gas diffusion electrode base material having a microporous layer on one side of an electroconductive porous base material， wherein the electroconductive porous base material comprises carbon fibers and a carbonized resin， and has a density of 0.25-0.39 g/cm 3 and a pore modal diameter falling within a range of 30-50 μm. The microporous layer comprises a carbonaceous powder and a fluorine resin， and has a surface roughness of 2.0-6.0 μm， a porosity of 50-95%， and a pore modal diameter of 0.050-0.100 μm.
