PURPOSE:To reduce mixture of phosphoric acid compound in recovered water by corrosion of phosphoric acid in supplying recovered water obtained by cooling and condensing water content included in combustion waste gas from a fuel reforming device or in air off-gas in which phosphoric acid from a phosphoric acid fuel cell is mixed to an ion exchange type water processing device. CONSTITUTION:Sedimentation chambers 46 are disposed in parallel along a flow direction to be separated by partition plates 45 under a water passage 51 provided spirally from an exit of a water collecting tube 49 comprising a water collecting plate 47 and a water guide tube 48 to collect recovered water cooled and condensed at a water content recovering tower 31 of a generated water recovering device 30. As the recovered water flows to the water passage 51, phosphoric acid compound included in the recovered water is settled as sediment in the sedimentation chambers 46. |
