POWER GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a technology which allows re-treatment of water stored in a water tank.

SOLUTION: A power generator 2 comprises: a fuel cell 80; a reformer 70; a water treatment device 30; a water tank 40; a supply pump 60; a circulation passage 200; and a circulation pump 20. The water treatment device 30 treats water to be supplied to the reformer 70. The water tank 40 stores water treated by the water treatment device 30. The circulation passage 200 is a passage for circulating water between the water tank 40 and the water treatment device 30. The circulation pump 20 circulates water through the circulation passage 200. By operating the circulation pump 20, the water stored in the water tank 40 can be supplied again for treatment to the water treatment device 30. Re-treated water having high purity is stored in the water tank 40 so that it can be supplied to the reformer 70.
