ULTRA-LIGHT BIPOLAR PLATE FOR FUEL CELL

摘要

PURPOSE: A bipolar plate for a fuel cell is provided to secure the chemical stability and the gas permeability, and to remarkably reduce the volume and the weight of the plate. CONSTITUTION: A bipolar plate(4000) for a fuel cell comprises the following: a non-conductive fuel membrane(30) including a fuel flow channel(32); an air electrode membrane(10) including an air flow channel(12); a non-conductive separator(20) capable of separating fuel and air by being installed in between the fuel membrane and the air electrode membrane; and a metal unit(60) supplying a current transfer path.
