    • The present invention relates to an improved method for manufacturing a PEMFC bipolar plate by which a water-repellent treatment is performed inside the radius of rotation of a short-shaft channel that rotates in a long-shaft channel as a main channel so that condensate water in a reaction gas flow path can be easily discharged. The present invention provides a method for manufacturing a PEMFC bipolar plate, which is a bipolar plate for a fuel cell that uses a stainless steel sheet, including: (a) a step for preparing the stainless steel sheet; (b) a step for treating a surface of the stainless steel sheet to be hydrophilic; (c) a step for molding a bipolar plate, which has a channel recessed to a first surface or a second surface, by pressing the stainless steel sheet; and (d) a step for molding an opening portion that penetrates the first surface and the second surface molded in the bipolar plate, in which the water-repellent surface treatment is performed through a process in which the masked surface of the stainless steel sheet not subject to the hydrophilic treatment is left in the short-shaft channel rotating in the long-shaft channel in the channel formed in the bipolar plate prior to the hydrophilic treatment step in the channel in an inside portion of the radius of rotation.
    • 本发明涉及一种用于制造PEMFC双极板的改进方法,其中在作为主通道的长轴通道中旋转的短轴通道的旋转半径内进行防水处理,使得冷凝水 在反应气体流路中可以容易地排出。 本发明提供一种制造PEMFC双极板的方法,该PEMFC双极板是使用不锈钢板的燃料电池的双极板,包括:(a)制备不锈钢板的步骤; (b)将不锈钢板的表面处理为亲水性的工序; (c)通过按压不锈钢板,将具有凹陷到第一表面或第二表面的通道的双极板成型步骤; 以及(d)用于模制穿透双极板中模制的第一表面和第二表面的开口部分的步骤,其中通过不锈钢板的掩模表面不进行处理的方法进行防水表面处理 在亲水处理步骤之前的亲水处理步骤中,在旋转半径的内部部分中的通道内,在亲水处理中留在短轴通道中在形成在双极板中的通道中的长轴通道中旋转。
