1 Results Recently increased interest is shown to proton conducting materials based on the alkaline polymer-inorganic acid complexes that is caused by a possibility of their application as the high-temperature electrolyte systems for various electrochemical devices (fuel cells,sensors,lithium power sources etc.).Complexes of inorganic acids with the alkaline polymers (polybenzimidazoles[1],polyvinylpyridines[2]) are characterized by high ionic conductivity at ambient temperatures (up to 10-2 Ω-1·cm-1) and thermal stability up to 200 ℃.However during the work of a fuel cell there is a problem of an opportunity of an acid washing away from a membrane,and,as a consequence,decreasing of the performance characteristics of the electrochemical device.
1 Results Recently Added interest is shown to proton conducting materials based on the alkaline polymer-inorganic acid complexes that is caused by a potential of their application as the high-temperature electrolyte systems for various electrochemical devices (fuel cells, sensors, lithium power sources etc etc .). Complexes of inorganic acids with the alkaline polymers (polybenzimidazoles [1], polyvinylpyridines [2]) are characterized by high ionic conductivity at ambient temperatures (up to 10-2 Ω-1 · cm- 1) and thermal stability up to 200 ° C. During the work of a fuel cell there is a problem of an opportunity of an acid washing away from a membrane, and, as a consequence, decreasing of the performance characteristics of the electrochemical device.
