First, second and third dopes (114, 115 and 116) containing a solid electrolyte are co-cast from a casting die (89) onto a running belt (82). The casting die (89) is provided with a feed block (119). A catalyst that promotes a redox reaction of electrodes in a fuel cell is added to the first dope (114) and the third dope (116). A casting membrane (112) having a three-layer structure is peeled from the belt (82) as a three-layered membrane (62) and sent to a tenter drier (64). In the tenter drier (64), the membrane (62) is dried in a state that both side edges thereof are held by clips, while stretched so as to have a predetermined width. The membrane (62) is then sent to a drying chamber (69) and the drying thereof is proceeded while supported by rollers. |
