Abstract
A fuel cell using an electrolyte-soluble fuel in which a solid film exhibiting a hydrogen ion- and/or hydronium ion-conducitivty is provided on the surface of an air electrode close to an electrolyte containing the fuel is disclosed. The solid film transmits hydrogen ions and hydronium ions, but it does not transmit water and oxygen in substance. Therefore, the leakage of electrolyte and the variation of the composition ratio of the electrolyte are not feared, so that the fuel cell can be used for a long time.
