PCT No. PCT/CA97/01012 Sec. 371 Date Aug. 28, 1998 Sec. 102(e) Date Aug. 28, 1998 PCT Filed Dec. 30, 1997 PCT Pub. No. WO98/29877 PCT Pub. Date Jul. 9, 1998The invention is a proton conductor in liquid form, comprising a mixture of the following components: (a) an acid addition salt of a nitrogen base, having the formula: wherein: Z1, Z2, Z3 and Z4, identical or different, each represent a group -N= or -C(Yi)= in which Yi represents a hydrogen atom, a linear or branched alkyl group having 1 to 20 carbon atoms, a fluoroalkyl radical having 1 to 20 carbon atoms, or an oxoalkyl or azaalkyl radical having 1 to 20 carbon atoms, with the proviso that at least one and at most two of the groups Z1, Z2, Z3 and Z4 represents -N=, two adjacent carbon atoms being optionally hydrogenated and the nitrogen base optionally being part of a polymeric network, and X- represents an anion derived from an acid selected from the group consisting of sulfonic acids of formula RFSO3H, sulfonimides of formula (RFSO2) (R'FSO2)NH and methylides of formula (RFSO2) (R'FSO2) CH2 or (RFS2) (R'FSO2) (R''FSO2)CH, in which RF, R'F and R''F each represents a radical F(CF2)n-, n being comprised between 0 and 6, the acid optionally being part of a polymeric network; and (b) a nitrogen base having the formula: in which Z1, Z2, Z3 and Z4 have the aforesaid meanings, the nitrogen base optionally being part of a polymeric network; components (a) and (b) being present in proportions to form a composition having a melting point lower than 25 DEG C. The proton conductor is useful as an electrolyte in various electrochemical systems.
