SOLID ELECTROLYTE MEMBRANE, METHOD AND APPARATUS OF PRODUCING THE SAME, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL

摘要

A dope (24) containing a solid electrolyte is cast from a casting die (81) onto a running belt (82). A casting membrane (24a) is peeled from the belt (82) as a wet membrane (25) containing the solid electrolyte. The wet membrane (25) is sent to a tenter drier (64) and dried therein to have a predetermined width in a state that both side edges thereof are held with clips (64a). The wet membrane (25) is then sent out of the tenter drier (64) as a membrane (62). The membrane (62) is sent to a drying chamber (69) and is further dried while being supported by rollers (68).
