Abstract
Official abstract text for this publication.
A proton conductor includes an anionic molecule and a cationic organic molecule. The anionic molecule is an anionic metal complex molecule. For example, the anionic metal complex molecule includes at least one chemical bond between a metal ion and an oxoacid ion. For example, the proton conductor can be used as an electrolyte membrane included in a fuel cell.
