PROBLEM TO BE SOLVED: To provide an apparatus of manufacturing a solid polymer fuel cell in which a catalyst layer has a uniform thickness, and swelling of the membrane is suppressed when forming a catalyst layer by coating the surface of an electrolyte membrane directly with a catalyst ink by means of a die coater, and then drying.SOLUTION: The apparatus of manufacturing a membrane electrode assembly for solid polymer fuel cell includes means for forming beads by supplying a catalyst ink containing at least a polymer material and a solvent onto one surface of an electrolyte membrane, means for coating one surface of the electrolyte membrane with the catalyst ink, by moving the electrolyte membrane placed on a suction plate by means of a conveyance roll and then sweeping the beads, and means for removing a solvent in the catalyst ink by volatilization, by heating the position of the electrolyte membrane corresponding to the beads, the part of the catalyst ink immediately after coating, and the remaining part of the catalyst ink after coating, from the other side of the electrolyte membrane. |
