FUEL-CELL SYSTEM

摘要

Fuel cell system (61) includes fuel cell (1), pre-condensation humidifier (4) that moves water from exhaust gas in a fuel cell unit that includes fuel cell (1) to a gas that is used for power generation in fuel cell (1), and condenser (2) that condenses water in the exhaust gas that has passed through pre-condensation humidifier (4). Fuel cell system (61) further includes post-condensation humidifier (3) that moves water from the exhaust gas that has passed through condenser (2) to a gas that is supplied to pre-condensation humidifier (4), a heat using unit that uses heat that is recovered from fuel cell 1, and a heat carrier circulation path that circulates a heat carrier through the heat using unit. The heat carrier circulation path is configured to cool down the exhaust gas that is supplied to the condenser so as to recover heat.
