Title:
FUEL CELL SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2014/129224
Kind Code:
A1
Abstract:
A fuel cell separator obtained by: roughening the surface of a compact formed by molding a composition containing graphite powder, an epoxy resin, and a phenol resin; treating the compact with infrared laser irradiation; and then performing a hydrophilizing treatment, wherein a fuel cell separator is provided having the characteristics that (1) the initial static contact angle is no greater than 20°, and (2) after manufacture, the static contact angle after being stored in atmospheric air for 3000 hours is no greater than 30°. This fuel cell separator has high hydrophilicity, allowing water generated during the electrical generation of the fuel cell to be easily discharged, and the hydrophilicity is maintained over a long period of time.
