  "textContent": "The invention aims to provide a polymer electrolytic material excellent in proton conductivity and also excellent in fuel shutting property, and accordingly provide a polymer electrolytic fuel cell with a high efficiency. That is, the invention provides a polymer electrolytic material having an unfreezable water ratio Rw1 defined by the following expression (S1) in a range of 20 to 100% by weight in hydrated state: Rw 1 = [ Wnf / ( Wfc + Wnf ) ] × 100 in which Wnf represents the unfreezable water content per 1 g of the polymer electrolytic material in dry state and Wfc represents the low freezing point water content per 1 g of the polymer electrolytic material in dry state.",
