Abstract
A reversible electrochemical system adapted to operate between a fuel cell mode, an electrolysis mode, and an electrolysis and fuel cell alternating mode(energy storage mode), operating on a fuel gas mixture and an oxygen-containing gas mixture. In the fuel cell mode, a current of electrons is delivered to an oxygen electrode where their charge is transferred to a plurality of oxygen ions which are passed through an electrolyte to a fuel electrode where the charge is transferred back to the electrode. In the electrolysis mode, a current of electrons is sent to a fuel electrode where the charge is transferred to a plurality of oxygen ions formed by the decomposition of steam. The oxygen ions pass through an electrolyte to an oxygen electrode where the charge is transferred back to the electrons.
