Original Abstract Submitted
The present disclosure relates to a gas diffusion layer structure for a unit cell of a fuel cell, the gas diffusion layer structure includes a gas diffusion layer disposed between a catalyst layer and a separator of the unit cell of the fuel cell, in which the gas diffusion layer includes a microporous layer positioned adjacent to the catalyst layer, and a base layer positioned between the microporous layer and the separator, in which the base layer includes: a microporous layer adjacent region disposed adjacent to the microporous layer, and a gas channel adjacent region disposed adjacent to the separator, and in which the gas diffusion layer is pressed so that a solid volume fraction of the gas channel adjacent region and the microporous layer adjacent region increases to a target solid volume fraction.
