FUEL REFORMING METHOD AND APPARATUS FOR POWER GENERATION SYSTEM USING FUEL CELLS

摘要

The reforming method for a fuel cell power generation system comprises the steps of feeding the raw material gas to a main reformer to reform the raw material gas to the fuel gas, feeding the fuel gas to the fuel electrode of the fuel cell, introducing to a second reformer non-reformed raw material gas contained in a gas discharged from the fuel electrode, and reforming the non-reformed raw material gas with hydrogen produced upon a reaction at the fuel electrode of the fuel cell and a sensible heat of the gas discharged from the fuel electrode. This reduces an amount of non-reformed raw material gas in the system and improves a reforming conversion ratio of the system as a whole.
