1-17. (canceled)
A laminated electrolyte membrane comprising a first layer comprising a hydrocarbon polymer electrolyte as a major component, and a second layer comprising a fluoropolymer electrolyte and polyvinylidene fluoride as major components laminated on at least one side of the first layer, wherein
- the first layer and the second layer are laminated via a region in which components constituting both layers are mixed in a mixed region.
A method of producing a laminated electrolyte membrane, comprising:
- a) forming a first layer formed of a hydrocarbon polymer electrolyte;
- and
- b) forming a second layer by applying a solution A in which a fluoropolymer electrolyte and polyvinylidene fluoride are dissolved in an aprotic polar solvent on the first layer.
