FLOW FIELD PLATE AND MANUFACTURING METHOD THEREFOR, AND BIPOLAR PLATE AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2024/036558

A1

The present application provides a method for manufacturing a flow field plate for use in a fuel cell unit. The method comprises: forming, on a first side of a metal plate, a first flow field for flow of a reaction fluid, a reaction region of the first flow field comprising a first ridge portion defining a first flow channel. The forming the first flow field comprises the following steps: cutting out, in a first conductive adhesive film, a first pattern corresponding to the first ridge portion; and bonding the cut-out first pattern to the metal plate on the first side, so that at least 10% of the height of the first ridge portion measured from the top is formed by the first pattern. The present application further provides a method for manufacturing a bipolar plate for use in a fuel cell, and a flow field plate and a bipolar plate manufactured according to the described methods. According to the present application, the contact conductivity of the flow field plate can be improved, the flow field plate is easy to manufacture, and the manufacturing cost of the flow field plate is reduced.
