- an object of the present invention is to provide a solid polymer electrolyte membrane with higher performance and lower cost by optimizing the irradiation conditions of radiation.
- the present inventors have minimized radiation deterioration of the substrate by defining the absorbed dose, and by defining the type and energy of radiation according to the thin film.
- the present inventors have found that the radiation utilization rate can be greatly improved, and have reached the present invention.
- the present invention is a solid polymer electrolyte membrane, a method for producing the same, and a fuel cell described below.
- An electron beam accelerated at an accelerating voltage of 60 to 300 kV in a vacuum is passed through a dense fluorine resin film having a thickness of 10 to 50 ⁇ m through an electron beam transmission window, and the resin film is formed in an inert gas atmosphere.
- a method for producing a solid polymer electrolyte membrane which comprises irradiating an absorbed dose power to 50 kGy and graft polymerizing a polymerizable monomer.
- the electron beam transmission window force is a Ti foil of 3 ⁇ 4 to 30 ⁇ m, and the irradiation distance (distance between the electron beam transmission window and the resin film) is 30 cm or less.
- a method for producing a solid polymer electrolyte membrane is a Ti foil of 3 ⁇ 4 to 30 ⁇ m, and the irradiation distance (distance between the electron beam transmission window and the resin film) is 30 cm or less.
- a fuel cell comprising the solid polymer electrolyte membrane described in (7) above between a fuel electrode and an air electrode.
- the present invention by irradiating the resin film with an electron beam under a specific condition, it is possible to achieve a good grafting of the resin film, minimize radiation deterioration, and further reduce the thickness of the resin film. Even in the case of membranes, the utilization rate of electron beams can be high, and the apparatus cost and running cost can be reduced, and a high performance and low cost solid polymer electrolyte membrane can be provided.
- the resin film is preferably a dense fluorine-based resin film substantially free of pores because of its excellent fuel barrier properties, and those conventionally used for solid polymer electrolyte membranes are suitably used. You can select and use. There are no restrictions on the type of fluororesin, but it has excellent film properties and is suitable for radiation graft polymerization, so polytetrafluoroethylene, tetrafluoroethylene perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene.
- Monohexafluoropropylene copolymer and ethylene-tetrafluoroethylene copolymer are preferred, especially tetrafluoroethylene perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene Xafluoropropylene copolymer and ethylene-tetrafluoroethylene copolymer are preferred, and ethylene-tetrafluoroethylene copolymer is more preferred. These can be used in appropriate combination.
- the film thickness of the resin film is 10 ⁇ m to 50 ⁇ m. If the film thickness is less than 10 ⁇ m, the film strength is poor. If it becomes thicker than 50 ⁇ m, which tends to cause breakage and breakage, there is a risk of ionic conductivity being insufficient. As a method for producing a resin film having such a film thickness, extrusion molding is simple.
- the resin film is irradiated with an electron beam so that the absorbed dose is 1 to 50 kGy, preferably 1 to 30 kGy. If the absorbed dose is less than lkGy, the grafting reaction will be insufficient, and if it exceeds 50 kGy, the mechanical properties of the resin film will be significantly degraded due to radiation degradation.

- the electron beam is accelerated in vacuum at an acceleration voltage of 60 to 300 kV, preferably 70 to 150 kV.
- the acceleration voltage is less than 60 kV or above 300 kV, the utilization rate of electron beams decreases.
- the preferred thickness of Ti foil is 5-30 / m or less because of its corrosion resistance. 8-15 / 1 1 11 is preferred. If it is less than 5/111, there is a problem of pinholes if the strength is insufficient, and if it is 30 ⁇ or more, the utilization rate of electron beams decreases.
- the irradiation distance is preferably 30 cm or less, more preferably 3 cm or less. Beyond 30 cm, the electron beam is absorbed by the atmospheric gas, and the utilization rate of the electron beam decreases.
- the irradiation atmosphere is preferably an inert gas atmosphere such as N, He, or Ar.
- the oxygen concentration in the irradiation atmosphere is higher than lOOOppm, the radical may be inactivated.
- the temperature of the irradiation atmosphere is preferably 10 to 50 ° C. If it is less than 10 ° C, a cooling cost is required, and if it is higher than 50 ° C, radicals may disappear.
- the electron beam may be irradiated on only one side of the resin film, on both sides or on both sides at the same time, but it is preferable to irradiate both sides from the viewpoint of uniformity. In order to further increase the utilization rate
- grafting of a polymerizable monomer is performed.
- polymerizable monomers include styrene monomers such as styrene, ⁇ -methylstyrene, and trifluorostyrene.
- Multifunctional monomers such as difunctional benzene, diarylbenzene and triallyl cyanurate can be used, and these can be used alone or co-grafted.

- sulfonic acid groups can be introduced by bringing them into contact with chlorosulfonic acid or fluorosulfonic acid.
- the present invention also relates to a fuel cell in which the solid polymer electrolyte membrane is provided between a fuel electrode and an air electrode.
- the configuration and structure other than the solid polymer electrolyte membrane of the fuel cell are not limited, but the solid polymer electrolyte membrane of the present invention has a low methanol permeability, and thus a configuration of a direct methanol fuel cell is preferable. .
