Patent ID: 8071253

Claim:
An electrochemical cell, comprising: an anode; a cathode; and an electrolyte membrane having one side bonded to the anode and the other side bonded to the cathode and containing an ionic conductor, wherein the ionic conductor comprises: (a) a cation expressed by one of Formulae (1) and (2): R 1 R 2 R 3 HN + (1) where, in Formula (1), R 1 , R 2 , and R 3 each indicate any one of alkyl groups C1 to C18 except a structure in which R 1 â•R 2 â•R 3 R 1 R 2 HS + (2) where, in Formula (2), R 1 and R 2 each indicate any one of alkyl groups C1 to C18 except a structure in which R 1 â•R 2 ; and (b) an anion expressed by Formula (3): R 4 SO 3 âˆ’ (3) where, in Formula (3), R 4 indicates any one of an alkyl group and a fluoroalkyl group.
