摘要： PROBLEM TO BE SOLVED: To provide an evaluation method for objectively and highly reliably evaluating a gas diffusion property of a porous body used for a fuel cell. SOLUTION: Platinum is uniformly arranged on a rear side of the porous body. For example, the porous body and a catalyst layer containing platinum may be unified. Thus, the rear side of the porous body is made airtight, and test gas containing carbon monoxide is passed along a surface of the porous body. Carbon monoxide concentration in the test gas having passed on the surface of the porous body is measured, and the gas diffusion property of the porous body is evaluated using the measurement result.

摘要： PROBLEM TO BE SOLVED: To provide a gas diffusion layer of a fuel cell capable of maintaining water repellency for a long time, while securing conductivity. SOLUTION: The fuel cell is provided with a gas diffusion layer diffusing gas to be supplied to an electrolyte film. The gas diffusion layer is structured with a conductive porous body layer, of which, a part to be in contact with water molecules produced by power generation of the fuel cell is coated with water-repellent matter. Further, the water-repellent matter, existing at a part to be in contact with a catalyst layer, a separator or the like on the conductive porous body layer, is removed. With this, conductivity inhibition by the water-repellent matter with high electric resistance can be avoided. Further, since the part other than the contact part is surely coated with the water-repellent matter, degradation of water repellency due to degeneration of water or the like can be avoided.
