摘要： Temperature control system and method for a fuel cell system are disclosed. The temperature control system includes a state detector, a control selector, a normal controller and an internal model controller. The state detector determines whether the fuel cell system is in a leakage condition based on a dynamic transfer function from an air flowrate provided to the fuel cell system to a fuel cell temperature. The control selector selects to switch between the normal controller and the internal model controller based on a determined result. The normal controller is configured for controlling an air flowrate of the fuel cell system which is not in the leakage condition. The internal model controller is configured for controlling the air flowrate of the fuel cell system in the leakage condition to control the fuel cell temperature. A fuel cell system with the temperature control system is also disclosed.

摘要： An AC component ΔI addition unit of a diagnostic device superimposes an alternating current on an output current of a fuel cell. A Zn calculation unit calculates a cell impedance with respect to the alternating current with regard to any of a plurality of cells. A diagnosis unit diagnoses that any cell 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 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).

摘要： A method checks the gas tightness of a fuel cell system which has a fuel cell and a container for storing hydrogen gas. The container is connected to the fuel cell via a line along which a pressure sensor is arranged to measure a pressure of hydrogen gas flowing to the fuel cell. A quantity of hydrogen gas flowing to the fuel cell is calculated by a quantity/pressure relationship which describes a relationship between the pressure and the quantity of hydrogen gas. A current which is generated by the fuel cell is measured and a quantity of hydrogen gas which has been converted into electricity by the fuel cell is calculated by a quantity/current relationship which describes a relationship between the current generated by the fuel cell and the quantity of burnt hydrogen gas. The calculated quantities of hydrogen gas are compared with one another.

摘要： A fuel cell voltage monitor (12a, 12b, 40, 140, 440) detects and may respond to, a problematic operating condition at or near a fuel cell (10) or within a subset (n) of fuel cells, as in a fuel cell stack assembly (110). Two or more co-planar, spaced voltage leads or contacts in a fuel cell plane, as at a separator plate, detect the presence of a voltage difference within the plate/plane as an indication of an operating problem at or near the fuel cell. Placement of such arrangements of at least two spaced voltage leads at various subset intervals (n), of fuel cells in a stack assembly allow monitoring for such problems throughout the stack assembly, either by analysis of voltage difference between co-planar leads at respective individual fuel cells or by comparison of voltage differences between aligned pairs of voltage leads at opposite ends of a subset.
