  • Patent number: 6562496
    Abstract: A method of starting a solid oxide fuel cell system is disclosed. The method comprises pressurizing a main plenum to a first pressure. The main plenum comprises a first supply of fuel, blowers, and air control valves. The first supply of fuel and a first supply of air are directed to a preheated micro-reformer. A heated pre-reformate is created in the micro-reformer and discharged from the micro-reformer to a main reformer. The main reformer is preheated with the heated pre-reformate. A second supply of fuel and a second supply of air are introduced to the main reformer. A heated main reformate is created in the main reformer and directed to a waste energy recovery assembly. A cathode supply is heated in the waste energy recovery system and then directed to a solid oxide fuel cell stack in order to heat the solid oxide fuel cell stack. Methods of transitioning, operating, shutting down, and maintaining in standby mode are also disclosed.
