PROBLEM TO BE SOLVED: To provide an inexpensive gas flow plate (separator) capable of increasing electric conductivity, by using a conductive resin material containing copper powder, capable of injection molding, simplifying a working process, and reducing a production cost. SOLUTION: In a solid polymer electrolyte fuel cell in which electrodes are arranged on both sides of a solid polymer electrolyte film, and having a gas flow plate 11a in which gas flow grooves through which fuel gas is supplied to one side of the electrode and an oxidizing agent gas is supplied to the other side of the electrode are formed, the gas flow plate 11a is made of a conductive resin material containing copper powder. |
