description A gas diffusion electrode medium for a fuel cell, which has high water repellent performance and excellent anti-flooding performance, can exhibit high power generation performance, and has high productivity is provided. A long gas diffusion electrode medium is composed of a conductive porous medium having a microporous layer containing a carbonaceous powder and a water repellent substance on one surface of the conductive porous medium, in which 65% or more of linear cracks observed in the microporous layer from the top surface are inclined at 45° to 90° from a width direction of the gas diffusion electrode medium.
