Beschreibung
Zusammenfassung:	The present invention provides a proton conductor comprising SnP2O7. The present invention also provides a fuel cell that comprising a cathode, an anode, and an electrolyte membrane, in which one of these components comprises SnP2O7. The SnP2O7 has high ionic conductivity of about 10-1 to 10-2 S/cm at about 80° C. or greater when non-humidified. In addition, SnP2O7 is water-insoluble, and stable at high temperatures. These properties make SnP2O7 suitable to act as a non-humidified proton conductor, or a high temperature non-humidified proton conductor.
