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: Rw1=[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.

A radiation-sensitive composition containing a resist compound A, an acid generator B, and an acid crosslinking agent C. The resist compound A is (a) a polyphenol compound which is produced by the condensation of a C
5-45
aromatic ketone or aromatic aldehyde with a C
6-15
compound having from 1 to 3 phenolic hydroxyl groups, and, (b) its molecular weight is form 300 to 5000. The radiation-sensitive composition is solvent-soluble and exhibits a high sensitivity, high resolution, and high heat resistance.
