Patent ID: 8187756

Claim:
A fuel cell system equipped with an ion exchange resin member that removes impurities from a fluid discharged from a fuel cell, the ion exchange resin member being located inside a gas-liquid separator for separating gas and liquid by swirling the fluid in a discharge passage for the fluid to flow through, the fuel cell system comprising: a dispersion means for dispersing the fluid over, and making the fluid flow to, an entry-side surface of the ion exchange resin member, and being configured to distribute the fluid flow so that the fluid flows into the entire ion exchange resin member, the dispersion means is a fluid introducing member in which a plurality of through holes is formed, wherein: the fluid introducing member is configured as a case to accommodate the ion exchange resin member, the dispersion means includes a fluid passage formed around the outer periphery of the entry-side surface of the ion exchange resin member, and the fluid introducing member includes an inclined plane that is inclined downward from its outer periphery toward its central part, the plurality of through-holes being formed on the inclined plane.
