A fuel cell system comprising:
- a fuel cell stack;
- and
- a stack case containing the fuel cell stack,
- wherein the fuel cell system is mounted in a vehicle,
- a gap is formed between outer periphery of the fuel cell stack and inner periphery of the stack case;
- a plurality of ventilation air inlet holes that are arranged side by side in a horizontal direction, the plurality of ventilation air inlet holes extending through the outer periphery of the stack case and the inner periphery of the stack case to be connected to the gap, the plurality of ventilation air inlet holes being formed at a lower position of the stack case in a vertical direction in a side surface serving as an end of the stack case on a rear side of the vehicle and a side surface serving as an end of the stack case in a vehicle width direction other than a side surface serving as an end of the stack case on a front side of the vehicle, the side surface serving as the end of the stack case on the rear side being perpendicular to the side surface serving as the end of the stack case in the vehicle width direction;
- a ventilation air outlet hole connected to the gap is formed at an upper position of the stack case in the vertical direction;
- and
- the ventilation air inlet hole is equipped with a filter unit including a liquid-impermeable and gas-permeable filter body.
