An electrochemical capacitor (10) stores an electrical charge from an external source (40). The capacitor has a positive electrode (30) and a negative electrode, each electrode being a metal oxide. A solid, protonically-conducting electrolyte (25 ) is disposed between the positive and negative electrodes...http://www.google.es/patents/US5549989?utm_source=gb-gplus-sharePatente US5549989 - Electrochemical capacitor having a proton conducting solid electrolyte
