摘要： A method of storing electric energy from an AC source of a certain frequency, whose value is not pre-established and is even variable, in one or more redox batteries composed of a plurality of elementary cells electrically in series and having a certain cell voltage, is disclosed. The method is implemented in an outstandingly versatile system for storing energy in one or more redox batteries easy to realize and capable of storing energy in a redox battery in highly efficient manner independently of the electric characteristics with which it is generated, and capable of exploiting the redox battery even as a “buffer” for transforming energy from an electrical source of certain voltage and frequency characteristics for supplying it to a load or outputting it on the electricity distribution network at different electric characteristics.

摘要： By realizing or installing check valve liquid vein interrupters in each compartment of the battery the phenomenon of slow discharge of the retained volumes of electrolytes during long periods of inactivity of a redox flow battery, with the electrolyte pumps stopped altogether, can be practically eliminated with the effect that the battery is perfectly ready to deliver electric power immediately upon request even after prolonged periods of inactivity. Moreover, the presence of liquid vein interrupters on each compartment in either an outlet or an inlet port substantially preventing by-pass current during a not pumping phase, permits to increase the by pumping the electrolytes through the compartments of a battery stack intermittently, in other words in a pulsed manner, with a certain duty-cycle. Relatively brief pumping phases at relatively high flow rate alternated to phases of not pumping provide for a volumetrically adequate refreshing of the electrolytes present in the battery compartments and contrast the formation of gradients in the bodies of electrolyte.

摘要： A multicell assembly for a redox flow electrolyzer is constituted by alternately stacking pre-assembled elements, typically an electrode subassembly including porous mat electrodes on opposite faces of a conductive plate and a permionic membrane subassembly. Pressure drops in circulating the electrolyte solutions through respective cell compartments, in contact with fluid permeable three-dimensional electrodes in the form of porous mats, are reduced while enhancing evenness of electrolyte refreshing over the whole geometrical cell-area, by defining cooperatively interleaved flow channels in the porous mat electrode. Two interleaved orders of parallel flow channels are defined. All the parallel spaced channels of each order extend from a common orthogonal base channel formed along the respective inlet or outlet side of the electrolyte flow chamber, and terminate short of reaching the base channel of the other. The flow channels include comb-shaped flow distributing channelworks having parallel fingers which interleave with each other.
