Abstract
The present invention provides, as a separator for fuel cell which is lightweight, can be easily made thin, and which has superior corrosion resistance and shape stability, a fuel cellcontaining a separator for fuel cell, wherein a conductor patternis formed on one principal planeA of an insulation layerto form a groove for a gas flow pathsectioned by the conductor patternon this principal plane, a conductor terminalis formed on the other principal planeB of the insulation layer, and this conductor terminaland the conductor patternare electrically connected by a via holepenetrating the insulation layer, and a membrane electrode assembly (complex having an electrolyte membrane and an electrode (fuel electrode, oxygen electrode) laminated thereon)having the separator for fuel cell disposed on both surfaces.
