SEPARATOR FOR FUEL CELLS AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention alleviates the problems of the prior art, and provides a fuel cell separator which is low in cost and high in hydrophilicity and electrical conductivity and a process for producing the fuel cell separator. The fuel cell separator of the present invention is characterized in that by using a starting material for fuel cell separator subjected to a hydrophilization treatment in a hydrophilizing gas, the surface contact angle of fuel cell separator as measured by a sessile drop method using water is in a range of 3 to 70 DEG ; and the process of the present invention for producing a fuel cell separator is characterized in that a starting material for fuel cell separator after molding or machining is subjected to a hydrophilization treatment in a hydrophilizing gas and thereby the surface contact angle of fuel cell separator as measured by a sessile drop method using water is controlled at 3 to 70 DEG .
