Abstract: A fuel cell has a fuel cell main body, a fuel supply unit, a voltage sensor, a supply speed determining unit, a fuel supply control unit, and a connecting unit. The voltage sensor measures the open-circuit voltage of the fuel cell main body. The supply speed determining unit determines the fuel supply speed of the fuel supply unit, on the basis of the results obtained from the measurement performed by the voltage sensor, in the case where the voltage measured by the voltage sensor is smaller than a predetermined value. The fuel supply control unit controls, on the basis of the supply speed thus determined, the fuel supply from the fuel supply unit. The connecting unit connects a load to the fuel cell main body, in the case where the voltage measured by the voltage sensor is larger than the predetermined value.
