  • Method for modifying surface of metal bipolar plate and bipolar plate for fuel cell
    Patent number: 9640806
    Abstract: A bipolar plate for a fuel cell is provided, which includes: a metal substrate having a flow field structure; a conducting adhesion layer formed on the metal substrate and having a polymeric adhesive and a plurality of conductive particles; and a pure graphite layer formed on the conducting adhesion layer and structurally corresponding to the flow field structure of the metal substrate. The graphite layer including expanded graphite powder is adhered to the metal substrate via the conducting adhesion layer, and a portion of the expanded graphite powder is embedded into the conducting adhesion layer.
    Type: Grant
    Filed: October 19, 2016
    Date of Patent: May 2, 2017
    Assignee: Industrial Technology Research Institute
    Inventors: Ho-Yen Hsieh, Wen-Lin Wang, Ching-Ying Huang

  • Method for modifying surface of metal bipolar plate and bipolar plate for fuel cell
    Patent number: 9515325
    Abstract: 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.
