A polyelectrolyte material includes as a main chain: a benzene ring; an ether; and a carbonyl group. A part of the benzene ring is sulfonated. A method for manufacturing a polyelectrolyte material includes: synthesizing disulfonyl difluorobenzophenone; and polymerizing the disulfonyl difluorobenzophenone, 4,4'-difluorobenzophenone, and phenolphthalein with a crown ether as a catalyst. The synthesizing is performed by reacting 4,4'-difluorobenzophenone with fuming sulfuric acid, performing salting-out the reaction product, and recrystallizing the salting-out product.
