Abstract: 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.

Abstract: A gas diffusion layer (GDL) for fuel cell applications that can prevented channels of a bipolar plate from being intruded. The gas diffusion layer is manufactured by cutting a GDL material at a certain angle such that a machine direction of the inherent high stiffness of the GDL material is not in parallel with a major flow field direction of a bipolar plate to prevent the GDL intrusion into the channels of the bipolar plate without modifying an existing method for manufacturing the gas diffusion layer. With the gas diffusion layer, the electrochemical performance of the fuel cell can be improved and manufacturing process can be improved even in the case where the width of the rolled GDL material is small.
