<P>PROBLEM TO BE SOLVED: To provide a water tank for a fuel cell vehicle in which a thawing time can be shortened and energy required to thaw can be saved. <P>SOLUTION: A pure water thawing tank 1 capable of freezing the pure water safely has a tapered protrusion 2 rising from the bottom face at its center part. An electric heater 10 as a heating means is installed at the pure water thawing tank 1, a thawing water storage tank 4 to temporarily store the thawing water, a diaphragm pump 5, and a piping 7. In the case the ice in the pure water thawing tank 1 is thawed, it is heated by supplying electricity to the electric heater 10. Because the water thawed in the pure water thawing tank 1 promptly flows down to the thawing water storage tank 4, contact of the ice with the wall face of the pure water thawing tank 1 is maintained, and thermal conductivity becomes superior. The water of the thawing water storage tank 4 is sprinkled on the ice in the pure water thawing tank 1 from a water spray port 8 via the diaphragm pump 5, a switching valve 6, and the piping 7, and the ice can be thawed quickly. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
