摘要： An electrochemical cell cooling system includes a closed loop for circulating coolant through an electrochemical cell. The loop includes a pump for pumping the coolant from a container through a filter and a heat exchanger. Pressure in the container and loop is selectively adjusted upwardly for a positive pressure condition or downwardly for a negative pressure condition using a pressure-adjusting flow line. The flow line includes a venturi in fluid communication with the container and a shut-off valve downstream of the venturi which is opened to induce depressurization of the loop or closed to cause pressurization. A variable-flow valve upstream of the venturi enables fine adjustment of the pressurization or depressurization. Alternatively, a flow-restricted bypass and a second variable-flow valve can be introduced to facilitate coolant temperature control.

摘要： A back pressure regulating device can be incorporated into a fuel cell test station or a fuel cell power module. For each of fuel can oxidant lines, it provides a gas pressure regulator. The pressure regulator is controlled by a pilot gas, supplied through a pressure regulating valve and a three-way valve. Another port of the three-way valve provides a vent through a check valve and a needle valve. The needle valve is connected to both check valves for the pilot gas lines for the fuel and oxidant. In normal operation, the pilot gas pressure, regulated by the pressure regulating valve, is supplied to the appropriate pressure regulator to control the respective fuel and oxidant gas pressures. On shut down, the three-way valve connects the pressure regulator through the respective check valve to the needle valve. This provides controlled decay of the pressures of the fuel and oxidant gases.

摘要： A system for treating process fluids delivered to an electrochemical cell stack is described. The system includes a treatment unit capable of treating and imparting a first range of temperatures to a process fluid that includes the freezing point of water. A filter removes ice particles larger than a particular size formed when the first temperature unit imparts a temperature to the process fluid low enough to cause ice particles to form.

摘要： A fuel cell testing station has a coolant supply line connected between the station and the fuel cell stack for supplying coolant to the fuel cell stack. The coolant supply line includes a flow control valve, a flow meter and a first temperature sensor. A coolant return line is connected between the fuel cell stack and the station for returning coolant to the station. The coolant return line includes a second temperature sensor. A coolant flow controller controls a coolant flow rate by actuating the flow control valve in response to feedback from the flow meter and from the first and second temperature sensors. Optionally, a variable-frequency drive is disposed in the coolant supply line to extend the range of coolant flow rates.

摘要： An apparatus and methods for detecting and identifying faults in a fuel cell are disclosed. An impedance spectrum relating to the fuel cell is compared with fault criteria to identify fault conditions in the fuel cell. A time-varying current is drawn from the fuel cell at a selected frequency and the impedance of the fuel cell at the frequency is measured. This may optionally be repeated at a range of frequencies or at combinations of frequencies to provide an impedance spectrum across the range of frequencies. The fault criteria identify one or more fault conditions that may be identified by comparing the measured impedance spectrum to the fault conditions.
