GAS DIFFUSION ELECTRODE SUBSTRATE, AND MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL EQUIPPED WITH SAME |
| 摘要 |
A gas diffusion electrode substrate that is used in a fuel cell and is constituted by an electrode substrate and microporous parts, in which a microporous part (A) is formed on one surface of the electrode substrate with a thickness in the range of 10 μm or more and 60 μm or less, and in the gas diffusion electrode substrate, the pore volume of pores with a pore size of 0.1 μm or more and less than 10 μm is within the range of 0.9 times or more and 5 times or less of the pore volume of pores with a pore size of 10 μm or more and less than 100 μm. |
