摘要： Provided is a fuel cell system capable of ensuring responsiveness during acceleration even when a motor with a smaller torque as compared to the related art is used. A control apparatus reduces the revolution speeds of motors of an air compressor, a circulation pump and a cooling pump by a coasting operation, without performing a regenerative control, when a load required from a fuel cell (electrical power required by various motors and auxiliary apparatuses) is being reduced and a travel speed is equal to or higher than a set speed. With such a configuration, even when a driver later reaccelerates a vehicle by, for example, pressing down an accelerator, required acceleration force is smaller as compared to the related art, and thus a motor with a small torque can be employed.

摘要： The procedure of the invention successively obtains an estimated value of amount of liquid water in a fuel cell during operation in each specified period by the following steps (a) to (d), thereby improving the detection accuracy of the water condition inside the fuel cell. The step (a) obtains a previous estimated value. The step (b) obtains a drainage rate that represents an amount of liquid water discharged from the fuel cell per unit time, based on the previous estimated value and a value representing a current flow rate of a reactive gas in the fuel cell. The step (c) multiplies the drainage rate by a period of obtaining the estimated value, so as to calculate an amount of liquid water discharged from the fuel cell for a specified duration. The step (d) determines a current estimated value, based on the amount of liquid water discharged from the fuel cell for the specified duration.

摘要： The pressure-adjusting valve provided in the cathode outlet of a fuel cell stack constituting a fuel cell system has a function of adjusting the oxidizing gas pressure in the fuel cell stack according to the adjustment of the valve opening degree. When the exhaust pipe is flooded with water, the pressure inside the exhaust pipe varies from the atmospheric pressure and the opening degree of the pressure-adjusting valve changes. The flooding estimation signal output processing unit of the control unit outputs a flooding estimation signal indicating that the exhaust pipe is flooded when an opening degree difference that is a difference between the opening degree of the pressure-adjusting valve and a preset opening degree corresponding to the operation directed pressure is equal to or greater than a preset threshold opening degree difference. The processing of inhibiting the flowing is performed based on this signal.
