Abstract: An ion exchange resin member 20 that serves as an impurity remover for removing impurities from fluid F discharged from a fuel cell 100 is placed in a discharge passage for the fluid F to flow through, and a dispersion means for dispersing the fluid F over, and making the fluid F flow to, an entry-side surface 21 of the ion exchange resin member 20 is placed upstream from the ion exchange resin member 20. Also, a gas discharge part and a liquid discharge part are placed downstream from a fluid outlet of the ion exchange resin member 20, and a liquid-movement-preventing means for preventing a liquid in the fluid discharged from the fluid outlet from moving toward the gas discharge part is placed between the ion exchange resin member 20 and at least either the gas discharge part or the liquid discharge part.

Abstract: A fuel cell system (1) capable of securely removing moisture in particulate form floating in an exhaust gas passage along with impurities mixed in the moisture, enhancing the performance of a fuel cell, and extending the service life of the fuel cell. The fuel cell system (1) includes a gas circulation system for recirculating and resupplying an exhaust gas to a fuel cell (100). This gas circulation system is equipped with an ion exchange resin member (20) that adsorbs impurity components contained in the moisture particles mixed in the exhaust gas flowing through the gas circulation system. The gas circulation system resupplies fluid that has passed through the ion exchange resin member (20) to the fuel cell (100).
