Beschreibung
Zusammenfassung:	A fuel cell separator which is obtained by molding a composition that contains a carbonaceous material and a resin, and which is provided with a sealing part and a groove that serves as a gas flow channel on one surface or both surfaces. This fuel cell separator is configured such that the arithmetic mean heights Sa of the surface of the sealing part and the bottom surface and the peak of the groove on at least one surface are 0.50-1.60 µm and the profile peak heights Spk thereof are 1.50 µm or less as determined in accordance with ISO 25178-2 (2012). Consequently, this fuel cell separator has good hydrophilicity and good adhesion to a gasket.
