Gas diffusion electrode substrate
摘要:
A gas diffusion electrode substrate that is used in a fuel cell, wherein a microporous layer constituted by a carbon based filler and a fluororesin is formed on one surface of the electrode substrate, the sliding angle of water on the surface on the opposite side of the surface on which the microporous layer is formed is 30 degrees or less, and the through-plane gas permeation resistance is 15 to 190 mmAq.
