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.
