摘要： A fuel cell manufacturing method capable of easily forming an interconnector part electrically connecting adjacent unit cells in a planar array fuel cell is provided. The interconnector part (30) is formed through a local heating process of carbonizing a proton conductive resin by locally heating an electrolyte membrane (12). The local heating process includes: a first heating step of heating a part of the electrolyte membrane (12) to a temperature equal to or less than a first temperature at a first temperature increase rate or less; and a second heating step of heating the part of the electrolyte membrane (12) to a temperature equal to or greater than a second temperature higher than the first temperature at a temperature increase rate greater than the first temperature increase rate, after the first heating step.

摘要： To provide a method for producing a fuel cell membrane electrode assembly that can prevent the required catalyst layer from being removed, while suppressing damage to the electrolyte membrane. A method for producing a fuel cell membrane electrode assembly MEA includes: a step of bonding a polymer electrolyte membrane PEM and a first catalyst layer-including substrate GDE1; a step of making a cut CL so that the first catalyst layer-including substrate GDE bonded with the polymer electrolyte membrane PEM becomes a predetermined shape; a step of peeling an unwanted portion GDE12 of the first catalyst layer-including substrate GDE1 from the polymer electrolyte membrane PEM; a step of irradiating a laser beam LB2 penetrating the polymer electrolyte membrane PEM without penetrating the first catalyst layer-including substrate GDE1 onto the polymer electrolyte membrane PEM, and removing residue RD of the first catalyst layer-including substrate GDE1 adhering on the polymer electrolyte membrane PEM.

摘要： A laser machining apparatus 1 includes: a laser head that is supported by a laser moving device so as to be movable in X, Y, and Z directions above a motor driven conveyor that transports a workpiece loaded thereon. The laser head includes protection glass for protecting a laser focusing lens; an ultraviolet irradiation device disposed beside the conveyor such that a laser light axis and an ultraviolet ray axis are parallel to each other; and a control device that controls the components of the laser machining apparatus so that the ultraviolet irradiation device radiates UV rays on the protection glass in a state in which a UV irradiation port faces a laser irradiation port of the laser head, thus cleaning the protection glass without removing it from the laser head.

摘要： A method for bonding electrical conductors is provided that is capable of suppressing a power source capacity when assembling a stator having a specific structure. First, coil pieces 9 are arranged in contact with bonding portions of a slot coil 5 inserted in a slot of a stator iron core 2 via a metal paste. Subsequently, an electrical current is applied using a pair of electrodes 11A and 11B in the axial direction (upward and downward in the figures) of the slot coil 5 while contact portions 15 between the slot coil 5 and the coil pieces 9 are pressed in an axial direction of the slot coil 5. As a result, electricity flows in the axial direction the coil piece 9 (a direction of an arrow X in the figures).
