PURPOSE:To eliminate the negative pressure on the suction side of an ejector and to improve reliability by providing a bypass pipeline for bypassing a part of the gaseous mixture of steam and raw fuel into a pipeline on the raw fuel inlet side to a pipeline on the delivery side of the ejector and to a pipeline on the raw fuel inlet side of the ejector. CONSTITUTION:The steam with the flow rate controlled by a steam flow rate transmitter 6 is introduced into the ejector 5 which is driven to suck raw fuel through a flow control valve 2, and the gaseous mixture of the raw fuel and steam is supplied to a reformer 7 to generate gaseous hydrogen. In this case, the bypass pipeline 8 for bypassing a part of the gaseous mixture of the steam and raw fuel into the pipeline on the raw fuel inlet side is provided to the pipeline on the delivery side of the ejector 5 and to the pipeline on the raw fuel inlet side of the ejector 5. As a result, the negative pressure on the suction side of the ejector 5 is eliminated, the flow rate of the raw fuel is easily controlled, and a decrease in the adsorption performance of a desulfurizer 4 is prevented. |
