PROBLEM TO BE SOLVED: To reduce cost by manufacturing a separator plate of a polymer electrolyte fuel cell through injection molding of a specific resin. SOLUTION: The polymer electrolyte fuel cell comprises a hydrogen ion conducting polymer electrolyte membrane, a pair of electrodes arranged on opposite surfaces of the membrane, and a pair of conductive separators having gas passages for supplying and exhausting one electrode with and of fuel gas and supplying and exhausting the other with and of oxidizer gas, and the conductive separators are a structure, having a polymer of long-chain diamine represented by general formula 1 and a conducting agent, in which formula 1 is an integer of 5 or greater and m is an integer of 100 or greater, showing a polymerization degree. A manufacturing method of the polymer electrolyte fuel cell comprises a mixing process for raw materials, having the polymer of long-chain diamine and the conducting agent, a hardening process of hardening the raw materials, and an injecting process of injection-molding the raw materials or hardened mixture. |
