A laser processing apparatus includes: a work support portion which supports the work and forms a closed space between the work and the work support portion; pads which are movable upward and downward inside the closed space and include upper surfaces respectively coming into contact with regions obtained by dividing a processing object region having the through-holes formed in the work to surround the region of the work over one circle when the pads move upward; a drive unit which drives the pads to move forward and backward between a state in which the pad is in contact with the work and a state in which the pad is separated from the work; a gas supply unit which supplies a gas into the closed space; and clamps which contact the work supported by the work support portion on inner circumferential surfaces and outer circumferential surfaces from above over one circle.

Laser processing apparatus and laser processing method

A method of producing an MEA includes a first joining step of joining an anode to one surface of a solid polymer electrolyte membrane to thereby form a joint body and a second joining step of joining a cathode to another surface of the solid polymer electrolyte membrane. In the first joining step, the solid polymer electrolyte membrane is attracted by suction and heated through the anode placed on a suction/heating surface of a suction/heating plate. In the second joining step, a stack body of the joint body and the cathode is pressed and heated in a stacking direction, between the suction/heating surface and a heating plate.

Method of and apparatus for producing membrane electrode assembly

The present invention is a method for producing a porous metal body or a method for producing an electrode catalyst, which is capable of simplifying the production process and improving the production efficiency by not requiring a step of immersion in an acid treatment solution. A method for producing a porous metal body according to the present invention comprises: a step for forming a metal resin-containing layer, which contains a metal and a resin that has a lower melting point than the metal, on a base; and a step for obtaining a porous metal body by subjecting the metal resin-containing layer to a heat treatment, thereby sintering the metal and removing the resin from the metal resin-containing layer.
