SEPARATOR USED IN FUEL CELL, AND FUEL CELL

Abstract

A separator used in a fuel cell includes: a supply manifold hole for fuel gas; an exhaust manifold hole for the fuel gas; and a fuel gas flow path system causing the fuel gas to flow through an electricity generation portion of the fuel cell, the fuel gas flow path system including a first flow path portion directing the fuel gas from the supply manifold hole to the electricity generation portion, a second flow path portion facing the electricity generation portion and supplying the fuel gas to the electricity generation portion, and a third flow path portion directing the fuel gas from the electricity generation portion to the exhaust manifold hole. The third flow path portion includes a low-hydrophilicity flow path disposed at the vicinity of the exhaust manifold hole and includes a low-hydrophilicity surface.
