<P>PROBLEM TO BE SOLVED: To improve energy efficiency in a vessel, especially a submersible, and make the submersible smaller and lighter. <P>SOLUTION: Temperature difference generating equipment 30 is employed, which is mounted on a vessel and equipped with a pump 35, a heat exchanging part 31 for heating, a turbine 32, a heat exchanging part 34 for heat radiation, and a generating unit 33. The pump 35 raises the pressure of working fluid in a first state of a liquid phase, bringing it to a second state of a liquid phase. The heat exchanging part 31 for heating raises the temperature of the working fluid in the second state, bringing it to a third state of a gas phase. The turbine 32 expands the working fluid in the third state, bringing it to a fourth state of a gas phase. The heat exchanging part 34 for heat radiation lowers the temperature of the working fluid in the fourth state, bringing it to the first state. The generating unit 33 is connected to the turbine 32, generating electric power. Then, the heat exchanging part 31 for heating raises the temperature of the working fluid through exchange of heat with exhaust heat of a fuel cell mounted on the vessel. The heat exchanging part 34 for heat radiation lowers the temperature of the working fluid through exchange of heat with water surrounding the vessel and flowing at least in one of inward and outward directions from and into the vessel. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
