NOVELTY - A dope (24) containing a solid electrolyte and an organic solvent is made to flow-spread on a support from a spread die to form a spread film. The spread film is stripped off from the support, and set as a film material. The film material is dried and film consisting of solid electrolyte is formed. A functional layer is arranged at the surface contacting the film, after drying liquid in functional material, and a solid electrolyte film (62) is obtained.    USE - For manufacture of solid electrolyte film used for electrode membrane composite material of fuel cell (both claimed) used as power supply for robots, toys, portable generator, field lighting equipment, flashlight, motor vehicles, household appliances and portable devices, such as mobile telephone, mobile notebook personal computer, electronic still camera, personal digital assistance, video camera, handheld game machine, mobile server, wearable personal computer and mobile display.    ADVANTAGE - The high quality solid electrolyte film having high ionic conductivity and excellent mechanical strength is manufactured continuously, economically and quickly. The electrolyte film provides electrode membrane joint component having excellent electromotive force.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) manufacturing equipment (33) of the solid electrolyte film, which has a spread die for flow-spreading dope, a film forming apparatus for drying film material and forming film consisting of solid electrolyte, and an apparatus for arranging a functional layer at the surface of film, after drying the liquid in functional material;    (2) solid electrolyte film manufactured by the above method;    (3) electrode membrane composite material comprising the solid electrolyte film, an anode contacted with one surface of solid electrolyte film, and a cathode contacting another surface of solid electrolyte film. The anode produces proton from hydrogen-containing substance. The cathode produces water from proton passed through solid electrolyte film, and gas; and    (4) fuel cell comprising the electrode membrane composite material, and a collector contacting the composite. The collector delivers electron of anode and cathode.    DESCRIPTION OF DRAWING(S) - The figure shows the schematic view of solid electrolyte film manufacturing equipment.
