    摘要： The invention provides a manufacturing process for MEA that enables sufficient bond strength among an electrolyte membrane and electrode substrates even when the electrolyte membrane comprises a heat-resistant material such as an aromatic polymer.
    The process comprises pressure bonding an electrolyte membrane with catalyzed electrode substrates to form a membrane-electrode assembly, wherein a good solvent for the electrolyte membrane is applied to at least one of facing surfaces of the opposed electrode substrate and the electrolyte membrane prior to the pressure bonding. The electrolyte membrane may comprise a sulfonated aromatic polymer. The good solvent for the electrolyte membrane may be an aprotic dipolar solvent.

    摘要： A membrane electrode assembly for a polymer electrolyte fuel cell has superior power generation characteristics under low humidity conditions and superior starting characteristics under low temperature conditions. In the membrane electrode assembly for a polymer electrolyte fuel cell in which a polymer electrolyte membrane is disposed between a pair of electrodes containing a catalyst, the polymer electrolyte membrane has a polymer segment A having an ion conductive component and a polymer segment B not having an ion conductive component. Furthermore, in the case in which the polymer electrolyte membrane is immersed in'water at 90°C for 30 minutes, absorbed water which exhibits a thawing temperature of from -30 to 0°C is in a range from 0.01 to 3.0 g per 1 g of the polymer.
