(a) A step of applying a coating fluid comprising a catalyst and an ion-exchange resin, on a substrate to form a coating fluid layer. (b) A step of disposing a reinforcing layer 24 (34) on the coating fluid layer formed in the step (a) and then, drying the coating fluid layer to form a first catalyst layer 22 (a second catalyst layer 34) The process provides a catalyst layer whereby defects such as cracks are scarcely formed in the catalyst layer, and the bond strength is high at the interface between the catalyst layer and a reinforcing layer and at the interface between the catalyst layer and a polymer electrolyte membrane.

摘要： An electromagnetic generator includes a magnet assembly having permanent magnets magnetized in a direction of stacking so that surfaces thereof corresponding to the same pole face each other. A solenoid coil is positioned around the magnet assembly so that a position of the solenoid coil relative to the magnet assembly can be changed. Holding parts hold the solenoid coil so that a center of the solenoid coil in a winding axis direction corresponds to a plane position where the surfaces of the permanent magnets corresponding to the same pole face each other at a stop position. Repulsive magnets generate magnetic repulsive forces that maintain the magnet assembly separated from the repulsive magnets. A length of an end face of each permanent magnet in a direction perpendicular to the winding axis direction is equal to or larger than double a length of the permanent magnet in the winding axis direction.
