A fuel cell comprises a bipolar plate having a conductive and hydrophilic surface layer disposed on at least a portion of its exterior area. The surface layer comprises a conductive carbon material having a hydrophilic organic group covalently attached to its surface. A process of producing a bipolar plate and a fuel cell is also disclosed. 本发明涉及燃料电池双极板的传导性的和亲水性的表面改性，尤其涉及燃料电池，包括具有传导性且亲水性的表面层的双极板，所述表面层设置在双极板外表面的至少部分上。所述表面层包含具有亲水性有机基团的传导性碳材料，该亲水性基团共价连接在碳材料的表面。还公开了生产双极板和燃料电池的方法。
