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.
