  • Patent number: 8206857
    Abstract: A cogeneration system having flexible and controllable cogeneration loops. There is a first cogeneration loop to recover heat from a fuel cell power module, thereby producing a heat to electricity ratio between 0 and approximately 1.0. There is a second cogeneration loop to produce supplemental thermal energy for hot water generation and/or space heating. This loop can be connected or disconnected via switching valves depending on the thermal demands of hot water and/or space heating. This loop can also be useful to control the fuel processor temperature to prevent it from being overheated in cases when the fuel cell has low fuel utilization efficiency. With this second loop, it becomes possible to adjust the heat to electricity ratio at any desirable levels such as more than 2. It is also possible to produce the hot water at a higher temperature or superheated steam, which would have been difficult if only the first loop is used.

  • Patent number: 8097376
    Abstract: There is described a fuel cell power system including a fuel processor subsystem, a fuel cell subsystem, and a power conditioning subsystem. The fuel processor subsystem comprises a main module for producing hydrogen rich streams from a hydrocarbon fuel, a balance of plant module for auxiliary components, and a control and electronic module for monitoring and controlling the fuel processor subsystem. The fuel cell subsystem comprises a main module for generation of electric power and thermal energy from hydrogen rich streams produced by the fuel processor module and air, a balance of plant module for auxiliary components, and a control and electronic module for monitoring and controlling the fuel cell subsystem. Each module has individual components attached thereto, the modules being designed and manufactured separately and assembled together to form the respective subsystems.

  • Publication number: 20100190067
    Abstract: There is described a method for managing a fuel cell system having a fuel contaminator present in an anode reactant, the method comprising: monitoring a fuel contaminator concentration in the anode reactant of a fuel cell stack, the fuel cell stack having a plurality of individual fuel cell units each having a membrane electrode assembly (MEA); detecting an increase in the fuel contaminator concentration in the anode reactant; and increasing, when the increase in fuel contaminator concentration is detected, a concentration of a compound that chemically reacts with the fuel contaminator in the anode reactant by a mass transfer through a membrane in the fuel cell system to reduce the fuel contaminator concentration.
