摘要： A porous separator for a fuel cell is provided and features the shape of a passage aperture formed in a flow field plate. The modified shape of the passage aperture minimizes destruction of a gas diffusion layer or a membrane electrode assembly attributable to stress concentration. The porous separator has a flow field plate that includes a first contact portion that is in contact with a gas diffusion layer or a membrane electrode assembly; a second contact portion that is in contact with a coolant channel; and a connection portion that is connected between the first contact portion and the second contact portion. Additionally, a passage aperture is formed in the connection portion, wherein a portion of an inside surface of the passage aperture protrudes toward a center of the passage aperture.

The first conductive layer includes at least a conductive carbon material and a polymer. The second conductive layer includes at least a conductive carbon material and a polymer. The conductive porous layer satisfies at least one of the following two conditions: “the polymer in the first conductive layer is present with a high density at the surface of the layer in contact with the second conductive layer than at the surface not in contact with the second conductive layer” and “the polymer in the second conductive layer is present with a higher density at the surface of the layer in contact with the first conductive layer than at the surface not in contact with the first conductive layer.” This makes it possible to provide a conductive porous layer with good adhesion between the first conductive layer and the second conductive layer and with reduced film thickness variation in each conductive layer. The conductive porous layer of the present invention can be used for fuel cells, metal-air batteries, and the like.
