CONTACT PLATE FOR ELECTROCHEMICAL CELL

PROBLEM TO BE SOLVED: To provide a method for manufacturing a contact plate for a fuel cell having an end plate, a double-pole plate and a cooling material distribution structure from a composite material made of a cheap thermoplastic resin. SOLUTION: A contact plate for an electrochemical cell (7), made of the composite material of a graphite/thermoplastic resin having a graphite percentage of at least 80 % in mass, containing a functional element (16) necessary to carry reaction media (17, 24), and making an electrical contact with electrodes (2, 3) is designed in fluid engineering so as to be manufactured in an injection molding process without secondary processing. The making of an edge area and a seal of a non-conductive material for surrounding the contact plate is integrated into a multi-component injection molding process so that the whole of the contact plate including the edge area and the seal can be manufactured with a single mold for injection molding.
