A surface of the magnet supporting tool to be held in contact with the magnet is shaped such that a central part of an upper end is higher than the upper ends of the pair of supporting portions and an end part of the upper end is lower than the upper ends of the pair of supporting portions when the magnet is placed on the surface, the upper end having a slope connecting the central part and the end part.

Magnet cutting device

A field-pole magnet manufacturing apparatus fractures a magnet fixed on a die serving as a lower tool by causing a punch of an upper tool to press the magnet while in contact with the magnet. At least one projection is formed in the punch of the upper tool symmetrically with respect to the central position of the magnet in the width direction of the magnet.

A method is provided that modifies a catalyst layer of a membrane catalyst layer assembly, which is manufactured by transferring the catalyst layer formed on a transfer sheet onto an electrolyte membrane. In the catalyst layer correction method, presence or absence of a defect in the catalyst layer is detected. The defect is removed based on the size and position of the detected defect. The portion from which the defect has been removed is repaired by application thereto of a correcting ink corresponding to the catalyst layer.
