▎ 摘  要

NOVELTY - The method involves outputting (S1) resin in the form of separator using a three-dimensional printer to produce a separator molded housing. A concave portion is formed (S2) by applying acetone to the surface of the separator. A conductive adhesive is applied (S3) to the molded separator formed with the concave portions. A copper plating layer is formed (S5) on the surface by plating a copper metal. The resin is made of acrylonitrile butadiene styrene, carbon nanotubes, graphene and carbon nanofibers. The thickness of the copper plate molded housing is 0.7 to 1.7 mm. The copper salt is selected from one of copper sulfate, copper chloride, copper oxide, copper methanesulfonate and copper pyrophosphate. USE - Method for producing unit cell specimen for testing performance of polymer electrolyte membrane fuel cell. ADVANTAGE - The method enables identifying problems in advance before manufacturing a graphite separator so as to reduce testing cost of the graphite and improve economic benefits. The method enables improving economic feasibility when studying structural shape of electrically conductive parts and versatility of a test equipment by manufacturing a conductive structure for fastening with standardized unit cell test equipment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a PEMFC separator for fuel cell performance test. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a PEMFC separator for fuel cell performance test and a method for manufacturing a unit cell specimen.
