ABSTRACT:
A process for producing a membrane-electrode assembly for solid polymer electrolyte fuel cells, including providing a die having an inlet for introducing coating liquids, a linear exit for discharging the coating liquids, and at least one guide partition wall for partitioning the inlet into compartments extending to the linear exit and slanted relative to the direction in which a substrate facing the linear exit moves relatively to the die, introducing the coating liquids from the inlet, and passing the coating liquids through the compartments separately, and moving at least one of the die and substrate so that the substrate relatively moves at substantially right angles to the longitudinal direction of the linear exit of coat the substrate with the coating liquids and form catalyst layers.
