UNDERWATER VEHICLE COMPRISING AN ELECTROLYTICALLY ACTIVATED ELECTROCHEMICAL BATTERY

摘要

This underwater vehicle, which has an electrolytically activated electrochemical battery intended to produce electrical energy for powering said vehicle, the electrochemical battery having: - an electrochemical cell (3) for producing electrical energy, - a reservoir (4) intended to contain the electrolyte, - means (7) for circulating the electrolyte between the electrochemical cell (3) and the reservoir (4), these circulation means comprising a helico-centrifugal pump disposed axially in the reservoir and comprising a motorized wheel mounted in a rotary manner in a diffuser, is characterized in that the diffuser is in the overall shape of a dome for discharging the flow of electrolyte at the outlet of the pump in a direction approximately parallel to the axis of the pump and thus of the reservoir.
