FUEL CELL SEPARATOR MANUFACTURING METHOD AND FUEL CELL SEPARATOR

摘要

A fuel cell separator is manufactured by charging a powdered molding material into a mold and compression molding the powdered material at a pressure of 0.98 to 49 MPa. The powdered material is charged in varying amounts for respective predetermined regions of the fuel cell separator. This process enables the inexpensive mass production of even fuel cell separators having a complex channel geometry to a uniform density, uniform pore characteristics and a good precision.
