Abstract
The preset disclosure provides a catalyst layer that has a small contact resistance with a gas diffusion layer and excellent gas diffusion properties. The catalyst layer for a fuel cell has a uniform thickness and includes fibrous conductive members and catalyst particles. The fibrous conductive members are inclined relative to a surface direction of the catalyst layer, and a lengthwise direction of the fibrous conductive members, on average, matches a first direction.
