A device for forming electrolyte to be injected into the cell system of a galvanic battery of the special kind which is capable of high output during a comparatively short period. The cell system is composed of, preferentially bipolar, electrode plates into whose interstices electrolyte is supplied through an input duct. The electrolyte consists of water admixed with sulphuric and chromic acid, the water being supplied under pressure from a pressure souce and the chromic acid being formed during operation of the battery by dissolving a chrome compound in water. The invention is particularly characterized in that the battery comprises, for the purpose of forming chromic acid, a tank which is filled with chrome trioxide or with a slat of hexavalent chromic acid, into which tank water is supplied through its upper part and allowed to pass slowly downwarldy, the chromic acid thus produced being drawn off through the lower part of the tank. The initial rise of the chromic acid concentration in the electrolyte supplied to the battery after it has been started up can be enchanced by providing in the water supply pipe leading to the electrolyte imput duct, a chrome compound cartridge delivering chromic acid into the water flowing through. The cell system of the battery and its sulphuric acid tank may be placed in an enclosed housing, the remaining space of which is filled with a chrome compound, thus serving as a chromic acid forming tank. The sulphuric acid may be disposed in a collapsible bag, from which it is driven into the system by water pressure.
