An object of the invention is to provide a method of producing gasket for fuel cells, in which it is possible to prevent MPL from inhibiting an impregnation at a time of impregnating a GDL with a liquid rubber and thereby it is possible to form a sufficiently impregnated state. In order to achieve the object, in a method of producing gasket for fuel cells, in which a GDL (1) made of a porous material is impregnated with a liquid rubber after an MPL is coated on a surface of the GDL (1), the method comprises the steps of forming an MPL uncoated portion (4) without coating the MPL to a portion where a sealing property is necessary (2) in the GDL (1), by using a method such as masking or the like, at a time of coating the MPL to the surface of the GDL (1), and next impregnating the MPL uncoated portion (4) with the liquid rubber. |
