  • FUEL CELL SYSTEM CONTAINING HUMIDITY SENSOR AND METHOD OF OPERATING THEREOF
    Publication number: 20200161671
    Abstract: Various systems and methods disclosed herein may include a fuel cell system that may dynamically respond to changes in steam concentration in the fuel cell system. The fuel cell system may include a fuel cell stack that produces an anode exhaust stream, an anode recycle blower that receives the anode exhaust stream and outputs an anode recycle stream, and a humidity sensor configured to measure the steam concentration of the anode recycle stream. The fuel cell system may also include a master controller configured to receive steam concentration measurement from the humidity sensor and control the operation of the anode recycle blower and/or other components based on the steam concentration measurement.
    Type: Application
