摘要： An electrode material, particularly a gas diffusion layer, for a fuel cell is provided which prevents electrode exfoliation during the manufacturing process by optimizing a water repellent material incorporated in the gas diffusion layer. The resulting electrode made from the gas diffusion layer has a high discharge performance at a low cost. This gas diffusion layer contacts a catalyst layer to form an electrode of the fuel cell layer, and the catalyst layer in turn contacts a polymer electrolyte membrane of the fuel cell. The gas diffusion layer contains a fibrillatable, water repellent material, and is subjected to heat treatment below the melting point of the water repellent material to fibrillate the material.

摘要： A porous supporting carbon body of a gas diffusion layer is provided with a larger number of smaller pores at its catalyst layer side and a smaller number of larger pores at the other side, particularly with an appropriate distribution of finer mesh at its catalyst layer side and coarser mesh at the other side. As a result, a high performance polymer electrolyte fuel cell is obtained in which water generated at the catalyst layer is quickly sucked out to the gas diffusion layer, and is evaporated at the gas diffusion layer to be effectively exhausted to outside the fuel cell, so that excessive water can be prevented from retaining in the gas diffusion electrode, with the polymer electrolyte membrane being maintained at an appropriately wet condition.
