In a three-dimensional shaping method and a three-dimensional shaping apparatus, a shaping path of each of a plurality of layers includes an inner shaping path and outer shaping path for shaping an inner wall portion and outer wall portion that surround a space and are adjacent in an inward-outward direction. The progression directions of the inner shaping path and outer shaping path are the same direction.

Three-dimensional shaping method and three-dimensional shaping apparatus

In a three dimensional shaping method and a three dimensional shaping apparatus, when a three dimensional object is obtained by laminating a resin material having thermoplasticity, the resin material is melted, and the melted resin material is laminated in a chamber to form resin layers. Next, the pressure in the chamber is adjusted to maintain the temperature of each of the resin layers within a predetermined temperature range in the chamber.

Three dimensional shaping method and three dimensional shaping apparatus

An electrolyte membrane thickness measurement apparatus includes a detecting medium supplying portion configured to emit a detecting medium, a detecting portion configured to detect a metal catalyst, and an analyzing unit. A thickness direction profile of a detection signal is generated by the detecting portion, and first and second inflection points are determined in the thickness direction profile based on the intensity of the detection signal by the analyzing unit. The distance between the first and second inflection points is evaluated as the thickness of the electrolyte membrane by the analyzing unit.

Method and apparatus for measuring thickness of electrolyte membrane

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 GDE; 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 GDEof the first catalyst layer-including substrate GDEfrom the polymer electrolyte membrane PEM; a step of irradiating a laser beam LBpenetrating the polymer electrolyte membrane PEM without penetrating the first catalyst layer-including substrate GDEonto the polymer electrolyte membrane PEM, and removing residue RD of the first catalyst layer-including substrate GDEadhering on the polymer electrolyte membrane PEM.
