Abstract
Disclosed is an ion conductive film containing a composite body between an ion conductive polymer and a nitrogen-containing compound. The nitrogen-containing compound has an immobilized portion to the ion conductive polymer and exhibits an enantiomeric isomer structure when protonated. Alternatively, the nitrogen-containing compound is capable of assuming a chemical structure in which the multiple bond represented by the double bound is moved, with the atoms constituting the molecule not changing their positions.
