Abstract:
1. A fuel cell system incorporating a fluid supply device in a reaction gas supply system, the fluid supply device comprising: a flexible portion midway in a fluid supply piping; first filter means that traps foreign matter in the fluid on an upstream side of the flexible portion; second filter means that traps foreign matter in the fluid discharged from the flexible portion on a downstream side of the flexible portion; and pressurizing means that pressurizes fluid taken in from the upstream side and transmits the fluid to the downstream side, provided upstream of the flexible portion, wherein the first filter means is provided within the pressurizing means or between the pressurizing means and the flexible portion, a filter accuracy of the second filter means is lower than a filter accuracy of the first filter means so that the second filter means filters the foreign matter that has passed through the first filter means but has agglomerated in the flexible portion, and the reaction gas supply system is a fuel gas supply system.
