Abstract:
1. A composite electrolyte membrane comprising: a reinforcement layer made of a resin and having apertures therein; and an electrolyte layer made of a polymer electrolyte and laminated at least one main surface of the reinforcement layer, wherein, an axis X wherein the orthogonal coordinate system is fixed on a main surface of the reinforcement layer, the reinforcement layer has strength anisotropy in which the tensile modulus of elasticity in the direction of the X wherein, an axis X wherein, the orthogonal coordinate system is fixed on a main surface of the electrolyte layer, the electrolyte layer has size anisotropy in which the rate of size change in the direction of the X the reinforcement layer and the electrolyte layer are laminated such that the direction of the X
