Patent ID: 11211674

Abstract:
An electrochemical-type power supply source is provided with: an electrochemical stack generating electric power, in the presence, internally, of electrolytic fluid, provided with a number of distinct groups of galvanic cells and of a corresponding number of electrolyte inlet pipes for introducing electrolyte into respective groups of galvanic cells and with electrolyte outlet pipes for extracting electrolyte from respective groups of galvanic cells; a main tank, fluidically coupled to the electrochemical stack and containing electrolytic fluid; and a recirculation system, defining a circulation path of the electrolytic fluid between the main tank and the electrochemical stack. A valve system that can be coupled to the electrolyte inlet and/or outlet pipes and operatively controllable to modify hydraulic and electric characteristics of the circulation path, in response to a power delivery condition by the power supply source.
