Title:
METHOD OF MANUFACTURING METAL GLASS SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2006/059402
Kind Code:
A1
Abstract:
A method of easily manufacturing a metal glass separator with excellent corrosion resistance, strength, and conductivity at low cost. A metal glass sheet (10) is disposed in a metal mold (20) with groove-shaped recesses and projections placed in a chamber (30), the metal glass sheet (10) and the metal mold (20) are heated to a temperature between a glass transition temperature and a glass crystallization temperature, and grooves are formed in the metal glass sheet (10) by a hot press. Since the grooves are formed in the metal glass sheet by using the hot press, the metal glass separator can be mass-produced and, therefore, the manufacturing cost of the separator can be reduced. In addition, the rather large machining dimensions of the separator such as sheet area, groove height, and sheet thickness can be taken for the manufacture of the separator.
