ABSTRACT:
The underwater propulsion apparatus, which is mounted on a ship, has the anode and cathode electrodes including an anode compartment and cathode compartment whose electrode materials are separated from seawater in a central duct by the ion exchange membranes so that they are protected from poisoning by seawater. In the method utilizing the apparatus, the anode compartment and cathode compartment are supplied with moist hydrogen and moist oxygen, respectively, so as to substantially suppress the evolution of gas in the duct, which lowers the thrusting force.
