  "textContent": "A gas diffusion electrode including: a conductive porous substrate and a microporous layer on at least one side of the conductive porous substrate; in which the total of regions passing through the microporous layer in the thickness direction has an area ratio of 0.1% or more and 1% or less; and in which the microporous layer has a portion that has penetrated into the conductive porous substrate (hereinafter referred to as penetration portion), the penetration portion having a thickness ratio of 30% or more and 70% or less with respect to 100% of the thickness of the microporous layer. The gas diffusion electrode used for fuel cells affords fuel cells having high water removal performance and high power generation performance.",
