Abstract: A method for fabricating a bi-polar plate of a fuel cell and the bi-polar plate thereof are presented. A graphite film is formed first. Next, a polymeric material added with electrically conductive powder is coated on a surface of a metal substrate. The graphite film is disposed on the polymeric material and the polymeric material is hardened to form an adhesive layer, such that the graphite film is attached on the surface of the metal substrate.
