Abstract
The invention relates to a process for the storage and conversion of energy using a H<-2/O<-2 /H<-2 system by alternating the operating modes of electrolysis/ fuel reaction, whereby a cell consisting of an anode chamber, cathode chamber and an ion exchange diaphragm acting as electrolytes, is used. The invention is characterized by a process which proposes that bifunctional oxidation electrodes be used as electrodes in the anode chamber such that oxygen evolution takes place when the process is in electrolysis mode, and hydrogen oxidation takes place when the process is in fuel cell mode, and that a bifunctional reduction electrode is used in the cathode chamber such that hydrogen evolution takes place when the process is in electrolysis mode and oxygen reduction takes place when the process is in fuel cell mode.
