Abstract: An electrochemical-type power supply source for use in marine environment, is provided with: an electrochemical stack, which generates electric power in the presence, internally, of an electrolytic fluid; a first tank, designed to contain electrolytic fluid at a first temperature; a second tank, designed to contain electrolytic fluid at a second temperature, lower than the first temperature; a thermostatic valve, that mixes electrolytic fluid at a lower temperature with electrolytic fluid at a higher temperature, for generating a mixed electrolytic fluid to be introduced into the electrochemical stack at a controlled temperature for generating a desired electric power. The electrochemical power supply is further provided with an auxiliary tank, adapted to contain electrolytic fluid at a third temperature, higher than the first temperature; and the thermostatic valve is connected to the auxiliary tank and receives, at an input, the electrolytic fluid at the third temperature, as a higher-temperature electrolytic fluid, for generating the mixed electrolytic fluid, in a given operating condition.

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.
