Polymer electrolyte membrane, method for producing same, and membrane electrode assembly and polymer electrolyte fuel cell comprising same |
摘要 |
A polymer electrolyte membrane obtained by subjecting a sulfonated polyarylene membrane having an initial water content of 80-300 weight % to a hot-water treatment. A composite polymer electrolyte membrane comprising a matrix made of a first sulfonated aromatic polymer having a high ion exchange capacity, and a reinforcing material constituted by a second sulfonated aromatic polymer having a low ion exchange capacity in the form of fibers or a porous membrane.
