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.
