| abstract | This invention provides a membrane electrode assembly having sufficient water retention ability and a high level of battery performance even under a low humidification condition. This invention discloses a manufacturing method of a membrane electrode assembly which has catalytic layers on both surfaces of a polymer electrolyte membrane. This manufacturing method includes following processes: A coating process that a catalyst ink which contains catalyst loading particles, a polymer electrolyte and a solvent is coated on a single surface of each of two base substrates. An arranging process in which a polymer electrolyte membrane is arranged between the two base substrates in a way that each of the base substrate's surfaces on which the catalyst ink is coated faces the polymer electrolyte membrane. A transferring process in which the catalyst ink coated on the two base substrates is transferred to both surfaces of the polymer electrolyte membrane to form the catalytic layers. A peeling process in which the two base substrates, which are attached to both sides of the polymer electrolyte membrane via the catalytic layers, are peeled off from the polymer electrolyte membrane and the catalytic layers. In addition, this manufacturing method has the following features: Each surface roughness (SRa) of the catalytic layers formed on the polymer electrolyte membrane after the peeling process is in the 0.01-1.00 μm range. Each gloss value at 85° (cf. JIS (Japanese Industrial Standard) Z 8741) of a surface of said catalytic layers is in the 10-80% range. |
