This research is on the development of a new extrusion method of a fuel cell separator with an orthogonal channel. Separators are successfully produced separators by this new extrusion method. It is important to determine the most suitable extrusion condition to enable stable continuous production. We decided to attempt the production of a fuel cell separator with a serpentine channel, which is a complicated shape. However, its formation has so far been impossible by the method of supplying material from the upper surface of the separator with the serpentine channel. Supplying the material from the side of the product channel was proposed as a new extrusion method for separators like the serpentine type. The flow of the material at the time of product formation was observed and the flow of the material required to achieve stable production was controlled by the position and geometry of the front guide at the position from which the product is extruded.
