FIELD: electrical engineering; fuel cell battery for various power installations such as vehicles or emergency power supplies.
SUBSTANCE: proposed fuel cell battery has at least two series-connected fuel cells each incorporating anode with hydrogen-sorbing alloy, oxygen (air) cathode, and additional electrode connected in parallel with cathode and made in the form of nickel oxide electrode disposed between anode and cathode; all electrodes are provided with external power leads; series connection of fuel cells is made between anode lead of one fuel cell and additional electrode lead of other fuel cell; cathode lead of each fuel cell is connected to additional electrode lead by means of switching device. Additional electrode is isolated from anode by matrix electrolyte and from cathode, by liquid electrolyte. Fuel elements are integrated with respect to liquid electrolyte to form common electrolyte loop. Switching device may be made in the form of electromechanical relay, intelligent switch, isolating diode, controlled diode, thyristor, or field-effect transistor.
EFFECT: fast reset, enhanced specific power characteristics, elongated service life.
