FUEL CELL POWER GENERATING SYSTEM

摘要

PURPOSE:To eliminate the necessity of increasing a capacity of a steam separator according to fuel containing a large quantity of steam required for steam reformation and eliminate the necessity of generating excessive steam in the steam separator in preparation for instant fuel switching to fuel containing a large quantity of steam required for steam reformation in the case where power is generated by fuel containing a small quantity of steam required for steam reformation. CONSTITUTION:In a fuel cell power generating system constituted of at least a fuel processing system including a fuel cell system 21 and a reformer 8 and an exhaust heat recycling system including a cell cooling water system, the cell cooling water system is connected to the reformer via a steam supply line 32 having a steam flow rate control valve 48.
