Abstract:
1. A polymer electrolyte membrane, comprising: a proton-conducting polymer selected from the group consisting of a polymer represented by one of Formula 1 and Formula 4 and a combination thereof: wherein M is Al, Au, Co, Cr, Fe, Ce, In, Mn, Ti, or V; x is 0 or 1 depending upon a valence of M; y, y′ and y″ are independently integers ranging from 1 to 6; z, z′ and z″ are integers ranging from 10 to 1000; R′, R″ and R′″ are independently H, or an alkyl group; and a, b and c are determined depending upon a valence of M and range from 0 to 6, and the sum of a, b and c is not more than 6, but is more than 0; and wherein M is Al, Au, Co, Cr, Fe, Ce, In, Mn, Ti, or V; x is 0 or 1 depending upon a valence of M; m and m′ are integers ranging from 1 to 5; n and n′ are integers ranging from 5 to 1000; R d and e are determined depending upon a valence of M and range from 0 to 6, and the sum of d and e is not more than 6, but is more than 0.
