MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF GAS DIFFUSION LAYER FOR FUEL CELL |
| 摘要 |
The manufacturing method of a gas diffusion layer for fuel cell includes coating a first coating fluid for forming a microporous layer on one surface of a porous base material used for formation of a substrate layer, and coating a second coating fluid for water repellent treatment having a lower viscosity than viscosity of the first coating fluid on the other surface of the base material facing downward in a direction of gravity. |
