PROBLEM TO BE SOLVED: To provide a technique capable of reducing such possibility that there may occur a variation in an amount of reaction gas supplied to an electrode in a fuel cell.SOLUTION: A fuel cell includes a power module having a first gas diffusion layer and a first separator. A primary passage, a secondary passage and a passage wall are provided on a surface of the first separator in the installation state of the fuel cell. The first gas diffusion layer has an upper region and a primary flow lower region. The upper region and the lower region have a different degree in at least one of gas diffusion properties and hydrophilic properties in at least a part of each region. |
