Design, Fabrication, and Testing of 625KW MCFC Demonstrator

STAR Fuel Processor• Autothermal reformer• Substrate-based

catalysts (no pellets)• 200 kWth input • Automotive volume

(~75 liters) • Design focus on

gasoline • Under-vehicle “flat”

aspect ratio• Modular, serviceable

design

DuAlto – High Power Hybrid DG (2005)

• 75-300kW baseload DG–Simple product and BOP indicates low

cost

• Proprietary PEM-turbine hybrid technology

• >45% electrical efficiency

• Lower cost than traditional PEM technologies

–pressurization–scale–lower cost of turbine

• Field Tests Begin in late 2005
