초록 ▼

A reformer arrangement is provided for a fuel cell power generation system in which a raw material gas is reformed with steam to a fuel gas and the fuel gas is fed to a fuel electrode of a fuel cell for power generation. This reformer arrangement includes a main reformer for reforming the raw material gas to the fuel gas; a fuel cell for receiving the fuel gas to cause the power generation and to produce steam; and a second reformer for reforming with the steam non-reformed raw material gas discharged from the fuel electrode. In one embodiment, the second reformer includes a cylindrical or tubular main body. An entrance for the gas discharged from the fuel electrode is formed at one end of the main body, and an exit for the gas is formed at the other end of the main body. The reforming catalyst is placed in a space between the gas entrance and exit, and a lid is provided at one or both ends of the main body for loading and unloading of the reforming catalyst. In another embodiment, the reforming catalyst is divided into several blocks in the main body of the second reformer so that a block which is damaged by a carbonate is replaceable by new one. In still another embodiment, the second reformer has a double-cylinder structure. The reforming catalyst is placed in an inner cylinder or a inspace between the inner and outer cylinders. The inner cylinder or the space which does not carry the reforming catalyst is used as a passage for discharging the gas from the second reformer, and one end of the inner cylinder is communicated with one end of the outer cylinder.
