摘要： An AC component ΔI addition unit (510) of a diagnostic device (5) superimposes an alternating current on an output current of a fuel cell (10). A Zn calculation unit (520) calculates a cell impedance with respect to the alternating current with regard to any of a plurality of cells (10a). A diagnosis unit (530) diagnoses that any cell (10a) is subjected to hydrogen deficiency when an absolute value of the cell impedance exceeds (absolute value of a reference impedance + a predetermined value β). It is diagnosed that any cell (10a) is subjected to oxygen deficiency when the absolute value of the cell impedance is smaller than (absolute value of the reference impedance-a predetermined value α).

The impedance measuring device includes computation means configured to compute an impedance of the laminated battery on the basis of the alternating-current potential difference detected by the detection means and the alternating current output from the power supply means, and an element having an impedance of a prescribed value necessary to calculate a measurement error of the impedance. The impedance measuring device includes switch means configured to alternately switch a battery connection state for connecting the power supply means and the detection means to the laminated battery and an element connection state for cutting off connection to the laminated battery and connecting the power supply means and the detection means to the element. The computation means computes an impedance of the element and diagnoses a measurement state of the laminated battery or corrects the impedance of the laminated battery when the switch means is switched to the element connection state.

摘要： An electrochemical fuel cell assembly comprises a fuel cell stack having a fuel delivery inlet and a fuel delivery outlet. The fuel cell stack further includes a number of fuel cells each having a membrane-electrode assembly and a fluid flow path coupled between the fuel delivery inlet and the fuel delivery outlet for delivery of fuel to the membrane- electrode assembly. A fuel delivery conduit is coupled to the fuel delivery inlet for delivery of fluid fuel to the stack. A bleed conduit is coupled to the fuel delivery outlet for venting fluid out of the stack. A variable orifice flow control device coupled to the bleed conduit configured to dynamically vary an amount of fluid from the fuel delivery outlet passing into the bleed conduit as a function of one or more of the control parameters: (i) measured fuel concentration; (ii) measured humidity; (iii) cell voltages of fuel cells in the stack; (iv) impedance of fuel cells in the stack; (v) resistance of fuel cells in the stack. The variable orifice flow control device may be coupled to a recirculation conduit and may be configured to dynamically vary a proportion of fluid from the fuel delivery outlet passing into the bleed conduit as a function of the control parameters.

摘要： The present disclosure is directed towards a method and a system for monitoring the performance of an electrochemical cell stack. Monitoring can be performed remotely by measuring the voltage across the stack, and comparing the measured values to predetermined reference values to determine the condition of the stack. Monitoring of the stack voltage enables detection of performance decay, which in turn enables preemptive repair of the stack prior to catastrophic failure.
