Title:
THIN-SHEET MOLDED-MEMBER HAVING FINE THREE-DIMENSIONAL SURFACE PATTERN, FUEL CELL SEPARATOR, AND METHOD AND FACILITY FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/088154
Kind Code:
A1
Abstract:
[Problem] To provide: a sheet-like molded article that is suitable for producing, at low cost and in a simple manner, a lightweight and compact separator that is thin and has a small inter-groove interval, groove width, and groove depth, while having a large contact surface area with oxygen gas and hydrogen gas; and a method or the like for manufacturing same. [Solution] This sheet-like molded article (amorphous thin-sheet) is characterized in that: a metallic parent phase thereof, which forms a passive layer at the surface so as to provide anticorrosive properties, has, on the surface, a three-dimensional surface pattern such as a groove-like relief pattern; and particles of an electroconductive material component are present at the surface (or further at the rear surface thereof) on which said relief pattern is formed and penetrate the passive layer so as to be exposed out of the surface without forming a solid solution with the metallic parent phase. This grooved, sheet-like molded article may be manufactured by attaching the electroconductive material component to the surface of a mold having a groove-like relief pattern, which is an inverted three-dimensional surface pattern, forming a corrosion-resistant alloy-adhesion laminate by spraying said surface, and, immediately after the formation of said adhesion laminate, warm-pressing the adhesion laminate.
