  • HIGH EFFICIENCY AND RELIABLE FUEL CELL SYSTEM OPERATING AT NEAR 100% FUEL UTILIZATION
    Publication number: 20120034539
    Abstract: A fuel cell system 110 containing fuel cells 120 contacted by hydrogen containing gaseous fuel, generating spent gaseous depleted fuel which is recirculated to a hydrogen separation system 143, preferably a heat exchanger 144 and condenser 148 to remove water 150, after which it is mixed with fresh fuel 116 and recirculated to the fuel cells 120.

  • Recuperated atmosphere SOFC/gas turbine hybrid cycle
    Patent number: 7781115
    Abstract: A method of operating an atmospheric-pressure solid oxide fuel cell generator (6) in combination with a gas turbine comprising a compressor (1) and expander (2) where an inlet oxidant (20) is passed through the compressor (1) and exits as a first stream (60) and a second stream (62) the first stream passing through a flow control valve (56) to control flow and then through a heat exchanger (54) followed by mixing with the second stream (62) where the mixed streams are passed through a combustor (8) and expander (2) and the first heat exchanger for temperature control before entry into the solid oxide fuel cell generator (6), which generator (6) is also supplied with fuel (40).
