摘要： During an intermittent operation of the fuel cell, a demanded FC voltage calculation portion calculates a predetermined voltage that is below a heightened potential avoidance threshold voltage as a demanded FC voltage, and outputs the voltage to a converter. When during the intermittent operation of the fuel cell, a deviation obtained by subtracting a generated power of the fuel cell from a system's allowable power that is allowable in the fuel cell system becomes less than or equal to a value 0, the demanded FC voltage correction portion corrects a command value provided for the converter so that the deviation becomes equal to the value 0.

摘要： A method and a device for measuring various parameters of a membrane electrode assembly (MEA) in a fuel cell. Hydrogen gas and nitrogen gas or air are supplied to the fuel cell to be tested. A voltage of the fuel cell is diminished by connecting to a load until the voltage is zero. The fuel cell is charged at a constant current. A constant current value is measured by a current sensor. A current signal and a voltage signal are collected by a data collector and are converted into digital quantity signals which are transmitted to a data processing unit. Data are automatically processed by programming of the data processing unit. Parameters, including an electrochemical active surface area of a catalyst, a double-layer capacitance, a hydrogen crossover current, and an impedance of the MEA of the fuel cell are acquired by differentiation and integral operations of the voltage data.

摘要： The present invention relates to a fuel cell system that is capable of running a detailed diagnostic check on the internal dryness of a fuel cell. The fuel cell system measures the distribution of electrical current density on a power generation plane of the fuel cell, and diagnoses the internal dryness of the fuel cell in accordance with changes in the peak position of electrical current density on the power generation plane. If the fuel cell is configured to let a reactant gas (hydrogen) on the anode side and a reactant gas (air) on the cathode side flow in opposing directions with the power generation plane positioned in between, the fuel cell system judges whether the peak position of electrical current density is displaced toward the outlet of an anode or the outlet of a cathode. In accordance with the result of judgment, the fuel cell system can determine whether dry-up has occurred on the anode side or cathode side.

摘要： The present disclosure relates to systems and methods that may be used to predict a performance metric of a fuel cell. A system consistent with the present disclosure may include sensors in communication with the fuel cell stack, a performance metric prediction system, and a control system. The performance metric prediction system may determine a current density based on inputs provided by the sensors at a plurality of time periods, calculate a first parameter while the current density is below a lower threshold, and calculate a second parameter while the current density is above an upper threshold. The first parameter and the second parameter may be used to selectively adjust a fuel cell polarization curve over time. Based upon the polarization curve, a performance metric of the fuel cell stack may be predicted. The control system may implement a control action based upon the performance metric.
