FUEL CELL POWER PLANT

WIPO Patent Application WO2003043114

A3

A fuel cell stack (1) generates electric power by reacting air with hydrogen supplied from a hydrogen supply passage (4) and recirculates anode effluent resulting from power generation operations to the hydrogen supply passage (4) through a recirculation passage (8) via an ejector (10). A valve (12, 20) is provided for supplying hydrogen from the hydrogen supply passage (4) to the fuel cell stack (1) by bypassing the ejector (10). A controller (7) maintains the anode effluent recirculation performance of the ejector (10) when the hydrogen flow amount in the hydrogen supply passage (4) is small by regulating the opening of the valve (12, 20). When the hydrogen flow amount is large, the pressure in the hydrogen supply passage (4) upstream of the ejector (10) is prevented from excessive increases.
