wherein the two or more cylindrical cells comprise granular aluminia loaded into a plurality of granular-aluminium reactant chambers and storage spaces as anode reactant without necessity of removing unconsumed anode aluminium;
wherein an automatic refilling device is positioned and fixed on the convex lip of the air cover by connection through the buckle stakes on the cell house,
wherein a cathode-anode gap defined by an electrolyte ion-conductive chamber, within the two or more cells of the stack core, is unchanged as the granular aluminia is consumed, so that an internal resistance of the compact battery is kept unchanged when the compact battery discharges;
wherein a plurality of electrolyte-circulation channels within the stack core are defined through the stack-electrolyte-inlet nozzles, the electrolyte-inlet compartment, the sink electrolyte-intake nozzles, a first plurality of soft pipes, the electrolyte-inlet nozzle, the electrode electrolyte inlets, a plurality of anode electrolyte-circulation passageways, the electrolyte ion-conductive chamber, a plurality of electrode electrolyte outlets, the funnel-shape electrolyte room, the electrolyte-precipitate room, the sink-electrolyte outlet nozzles, a second plurality of soft pipes, and the stack-electrolyte-outlet nozzles which are connected to an electrolyte circulation system outside the stack core

wherein a plurality of hydrogen collection channels within the stack core are constructed through a plurality of current-hydrogen lead-out cylinders, a hydrogen-collecting room, the upper hydrogen-collecting room, and the hydrogen outlet nozzles which are connected to a hydrogen utilization system outside the stack core;
further comprising means for enhancing electrolyte-ion conductivity in the electrolyte ion-conductive chamber comprising:
electrolyte circulation in the anode electrolyte-circulation passageways to push aluminates and aluminium hydroxides in the electrolyte away from the granular aluminia in the plurality of granular-aluminium reactant chambers, into the electrolyte ion-conductive chamber and further into the electrolyte outlet sink,
a quantity of seed crystals, in the electrolyte outlet sink, which make part of the aluminium hydroxides precipitate into precipitates of first aluminium hydroxides so that some of the aluminates can be shifted into second aluminium hydroxides and second hydroxide ions,
an air-heat exchanger, in the electrolyte circulation system, which cools the electrolyte outside the stack core so that another part of the aluminates in the cooled electrolyte will decompose into third aluminium hydroxides and third hydroxide ions,
a precipitate-filtering pump, in the electrolyte circulation system, which removes the precipitates of the first aluminium hydroxides, precipitates of the second aluminium hydroxides, precipitates of the third aluminium hydroxides, from the cooled electrolyte so that the precipitates of the first, second, third aluminium hydroxides can not be reversed into the aluminates, and the second hydroxide ions, the third hydroxide ions can not be consumed during a subsequent process of electrolyte heating by a electrolyte heater in the electrolyte circulation system,
a pressure pump in the electrolyte circulation system to make the electrolyte with the second hydroxide ions, the third hydroxide ions return to the cells within the stack core;

means for enhancing oxygen-reduction reactions on the cylindrical cathodes of the cells within the stack core, and means for utilizing thermal energy of hot electrolyte through the air-heat exchanger, in the electrolyte circulation system, which makes use of the thermal energy of the hot electrolyte produced in the cells, and increases supplied air temperature within the cathode-air chamber, so that the oxygen-reduction reactions of the cells are enhanced with the increase of the supplied air temperature.
