  • Generation of oxygen depleted air by a fuel cell system
    Patent number: 10553886
    Abstract: The present disclosure is directed to a fuel cell system for generating oxygen depleted air. The fuel cell system may include a fuel cell having an anode, a cathode, and an electrolyte positioned between the anode and the cathode. The cathode may be configured to receive an air flow and discharge an oxygen depleted air flow. The fuel cell system may further include a sensor configured to generate a first signal indicative of a presence of hydrogen in the oxygen depleted air flow and a controller in communication with the sensor and the fuel cell. The controller may be configured to detect the presence of hydrogen in the oxygen depleted air flow based on the first signal, and in response to detecting the presence of hydrogen in the oxygen depleted air flow, selectively cause a current density of the fuel cell to decrease and/or increase a flow rate of the air flow to the cathode.

  • Technique and apparatus to measure a fuel cell parameter
    Patent number: 7099787
    Abstract: A technique includes introducing an electrical perturbation to a fuel cell system during operation of the fuel cell system. This electrical perturbation does not substantially disrupt the operation of the fuel cell system. In response to the perturbation, an electrical parameter of the fuel cell system is measured.
