Title:
FUEL CELL GENERATION SYSTEM AND ITS CONTROL METHOD
Document Type and Number:
Japanese Patent JP2009176659
Kind Code:
A
Abstract:
To improve the fuel utilization factor of a fuel cell generation system without increasing the power of an accessory.
The fuel cell generation system comprises a CO shift converter 4 for producing hydrogen and carbon dioxide with the reaction of carbon monoxide in fuel electrode exhaust gas 61 with water vapor, and hydrogen separation reservoirs 7, 8 for selectively reserving hydrogen in CO shift converter exhaust gas 15 and releasing the reserved hydrogen with the thermal energy of oxidant electrode exhaust gas 63, wherein the hydrogen released from the hydrogen separation reservoirs 7, 8 is recycled in a fuel cell. The hydrogen separation reservoirs 7, 8 alternately repeat the reservation and release of the hydrogen.
