  "textContent": "A gas diffusion layer (30) for a fuel cell includes: a gas diffusion layer substrate (31); and a microporous layer (32) containing a granular carbon material and scale-like graphite and formed on the gas diffusion layer substrate (31). The microporous layer (32) includes a concentrated region (32a) of the scale-like graphite that is formed into a belt-like shape extending in a direction approximately parallel to a junction surface (31a) between the microporous layer (32) and the gas diffusion layer substrate (31). Accordingly, both resistance to dry-out and resistance to flooding, which are generally in a trade-off relationship, in the gas diffusion layer can be ensured so as to contribute to an increase in performance of a polymer electrolyte fuel cell.",
