WATER TREATMENT DEVICE FOR SOLID POLYMER TYPE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a miniaturizable water treatment device for a solid polymer type fuel cell suitable for domestic use and capable of saving space and of reducing a cost, in a water treatment device for a solid polymer type fuel cell using, as water for the fuel cell again, pure water obtained by supplying an exhaust gas in the solid polymer type fuel cell to an exhaust gas condenser and by feeding the produced recovery water to a demineralizer.

SOLUTION: A sweep type film deaerator 10 for subjecting the recovery water to a decarbonation treatment is installed between the exhaust gas condenser 50 and the demineralizer 40. A blower for sweep air is omitted by partially shunting the air from an air-supplying blower 23B to an air electrode 23 (or a reformer 30) to supply it to a ventilation part of the film deaerator 10.
