PURPOSE: Provided is an auto-generation system having improved energy efficiency, which is equipped with an operation power supplying part supplying the electricity for driving a fuel cell so that the system is operated rapidly. CONSTITUTION: The auto-generation system comprises a reformer(12) generating hydrogen from a fuel and equipped with a burner(12b), and a fuel cell(10) comprising a stack(13) formed of an anode(13b) and a cathode(13c) separated by an electrolyte membrane and generating electricity and heat by the electrochemical reaction of hydrogen with oxygen, in which the hydrogen generated by the reformer or a hydrogen -containing fuel is supplied to the anode(13b), while oxygen or an oxygen-containing oxidant is supplied to the cathode(13c). Particularly, the auto-generation system comprises an operation power supplying part(20) supplying the electricity for driving the fuel cell, when the fuel cell(10) is initially operated or a load output is changed, and a controller(21) for controlling the operation of the operation power supplying part(20). |
