Method for modifying surface of metal bipolar plate and bipolar plate for fuel cell
A method for modifying the surface of a metal bipolar plate is provided. The method includes the steps of providing a metal substrate having a conducting adhesion layer on a surface thereof, the metal substrate having a flow field structure at the surface thereof; applying expanded graphite powder onto the conducting adhesion layer; and press-fitting the expanded graphite powder and the metal substrate with a mold structurally corresponding to the flow field structure, to form a graphite layer covering the surface the metal substrate from the expanded graphite powder. A bipolar plate for a fuel cell is further provided.
