ABSTRACT:
An electrochemical cell includes an electrolyte membrane containing an ionic conductor. The ionic conductor includes:(a) a cation expressed by one of Formulae (1) and (2):in-line-formulae description="In-line Formulae" end="lead"?R1R2R3HX+  (1)in-line-formulae description="In-line Formulae" end="tail"?where, in Formula (1), X indicates any one of N and P, and R1, R2and R3each indicate any one of alkyl groups C1 to C18 except a structure in which R1═R2═R3,in-line-formulae description="In-line Formulae" end="lead"?R1R2HS+  (2)in-line-formulae description="In-line Formulae" end="tail"?where, in Formula (2), R1and R2each indicate any one of alkyl groups C1 to C18 except a structure in which R1═R2; and(b) an anion expressed by Formula (3):in-line-formulae description="In-line Formulae" end="lead"?R4YOm(OH)n−1O−  (3)in-line-formulae description="In-line Formulae" end="tail"?where, in Formula (3), Y indicates any one of S, C, N and P, R4indicates any one of an alkyl group and a fluoroalkyl group, and m and n each indicate any one of 1 and 2.
