ABSTRACT:
A mixture, cation conductor and electrochemical device using same are provided. The mixture and a cation conductor, in which cations can be moved without humidification even in a range of temperatures less than or equal to the boiling point of water, or an electrochemical device such as a fuel cell using them. A fuel electrode and an oxygen electrode, which are oppositely arranged with an electrolyte film in between, is provided. The electrolyte film contains a first compound formed of an imidazole derivative containing N having an unshared electron pair and a second compound of at least one selected from the group consisting of compounds having structures shown below.
