| 20100224769 | Method of calibrating an apparatus for measuring radon and/or its progeny in an air sample - A method of calibrating an apparatus for measuring Radon and/or its progeny in an air sample, includes providing an apparatus for measuring Radon in an air sample that includes a preset offset voltage corresponding to a threshold conductivity value and a preselected reading value for indicating a concentration of Radon and/or its progeny, exposing the apparatus to a calibration area for measuring conductivity of the air therein, comparing the measured conductivity value of the air with the preset offset value for conductivity, and setting a lower threshold conductivity value and corresponding threshold reading value same as the preselected reading value, if the measured conductivity of the air is determined to be lower than the preset offset value for conductivity. | 09-09-2010 |

| 20090110966 | Method for Improving FCS Reliability After End Cell Heater Failure - A method for improving fuel cell system reliability in the event of end cell heater failure in a fuel cell stack. The method includes detecting that an end cell heater has failed. If an end cell heater failure is detected, then the method performs one or more of setting a cooling fluid pump to a predetermined speed that drives a cooling fluid through cooling fluid flow channels in the fuel cell stack, limiting the output power of the fuel cell stack or the net power of the fuel cell system, limiting the maximum temperature of the cooling fluid flowing out of the stack, turning off stack anti-flooding algorithms that may be used to remove water from reactant gas flow channels in the stack, and turning off cathode stoichiometry adjustments for relative humidity control in response to water accumulating in cathode flow channels in the fuel cell stack. | 04-30-2009 |
| 20100035097 | FUEL CELL STACK USED AS COOLANT HEATER - A system and method for increasing the temperature of a fuel cell stack quickly, especially at cold stack start-up. The method includes determining whether the fuel cell stack is below a first predetermined temperature threshold, and, if so, starting a cooling fluid flow through the stack and engaging a shorting circuit across the stack to short circuit the stack and cause the stack to operate inefficiently. The method then determines a desired heating rate of the fuel cell stack and calculates a cathode airflow to the fuel cell stack based on the desired heating rate. The method reduces the flow of cathode air to the stack if a minimum cell voltage is below a predetermined minimum cell voltage threshold and disengages the shorting circuit and applies vehicle loads to the stack when the stack temperature reaches a predetermined second temperature threshold. | 02-11-2010 |
| 20110091780 | IN-SITU FUEL CELL STACK RECONDITIONING - A method for reconditioning a fuel cell stack. The method includes periodically increasing the relative humidity level of the cathode input airflow to the stack to saturate the cell membrane electrode assemblies to be greater than the relative humidity levels during normal stack operating conditions. The method also includes providing hydrogen to the anode side of the fuel cell stack at system shut down while the membrane electrode assemblies are saturated without stack loads being applied so that the hydrogen crosses the cell membranes to the cathode side and reacts with oxygen to reduce stack contaminants. | 04-21-2011 |

| 20100190078 | SHUTDOWN STRATEGY FOR ENHANCED WATER MANAGEMENT - A system and method for providing a fuel cell stack purge to remove excess water during system shut-down. A compressor is operated at a shut-down speed to force water out of the cathode flow channels and draw water through the membrane from the anode flow channels so that a desired amount of water is removed from the fuel cell stack without over drying the membrane. The cathode shut-down purge flow can be introduced in the forward or reverse direction. Further, the flow of hydrogen fuel can be directed so that it flows through the anode flow channels in an opposite direction to push water out of an anode outlet manifold into the anode flow channels so that it will also be drawn through the membrane by the cathode airflow. Finally, a brief rehydration step is added after the shut-down purge to achieve the desired water content in the cells. | 07-29-2010 |
| 20110189569 | AUTO-LEARNING OF BASE STACK RESISTANCE FOR HFR BASED RH CONTROL - A method for determining membrane humidification by determining the membrane protonic resistance of a fuel cell stack at humidified conditions, and normalizing the base resistance of the fuel cell stack against the base resistance of a reference fuel cell stack. | 08-04-2011 |
