  • Patent number: 10079397
    Abstract: To provide a technique that allows prompt detection of leakage of fuel gas in a fuel cell system. A controller included in a fuel cell system performs a hydrogen leakage detecting process of detecting the occurrence of hydrogen leakage in the low-pressure zone based on the detected pressure in a low-pressure zone of an anode gas piping at a time of start-up of the fuel cell system. A controller uses at least one of a first condition and a second condition for determination as a determination condition in hydrogen leakage detecting process, and determines that there is no leakage of the reactive gas while the fuel cell stops generating power if the determination condition is satisfied.

  • Patent number: 10033072
    Abstract: A battery module for receiving battery cells provides cooling through a cooling fluid. Chilled fluid travels first to the hottest part of the battery module and then continues to gradually less hot areas. As the chilled cooling fluid absorbs heat and travels to cooler parts of the battery module, the heat transfer between the fluid and the battery cells decreases because the temperature differential between the cells and cooling fluid decreases, providing a more even temperature distribution across the battery module. The cooling fluid may be contained in a conduit associated with one or more cooling plates. A plurality of slots provide a precise mechanical support for each battery cell, increasing the heat conduction from the cell to the battery module, protecting the battery module from vibration and decreasing contamination in case of thermal runaway or other damage to the cells.
