A fuel cell system capable of accurately and precisely determining the wet condition inside a fuel cell. The fuel cell system includes a solid polymer electrolyte type fuel cell having a stack structure. The fuel cell is connected to an air supply system, a hydrogen gas supply system, an output system, and a control unit. The control unit receives flow rates of air and hydrogen gas which flow into the fuel cell, their pressures when exhausted, and a generated current measurement signal. The control unit calculates the amounts of water exhausted from the fuel cell as a gas component and as a liquid component and determines the water balance in the fuel cell. |
