摘要： The present invention relates to a process for operating a regenerative fuel cell (RFC). The process involves circulating a first electrolyte (electrolyte 1) through the negative chamber of the cell and a second electrolyte (electrolyte 2) through the positive chamber of the cell. Electrolyte (1) contains sulfide during the discharge cycle of the cell. Electrolyte (2) contains bromine during the discharge cycle of the cell. Decreases in ph in the electrolyte are compensated by circulating a fraction of other electrolyte (1) or (2) through the positive chamber of an auxiliary cell. A fraction of electrolyte (2), which has been made free of bromine, is circulated in the negative chamber of the auxiliary cell.

摘要： In the regenerative fuel cell, a positive chamber is separated from a negative chamber by a cation exchange membrane. The positive chamber comprises a positive electrode and a bromine-containing electrolyte. The negative chamber comprises a negative electrode and a sulfide-containing electrolyte. When the cell is in operation, the electrolytes are replenished using electrolyte from an electrolyte store (32, 34). In the method, the distribution of water between the two electrolytes is controlled by discharging the electrolyte(s), such that when the electrolytes are separated by a water permeable membrane (46), water will flow from the sulfide-containing electrolyte to the bromine-containing electrolyte by osmosis. The electrolytes are circulated through a container (43) which is divided by a water permeable membrane (46), under conditions wherein no current flows in the container between the two electrolytes.
