FUEL SUPPLY SYSTEM OF HIGH TEMPERATURE TYPE FUEL CELL AND HIGH TEMPERATURE TYPE FUEL CELL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fuel supply system applicable to either an internal reformation type and an external reformation type high temperature type fuel cell when natural gas and gasified gas are used as fuel, and to provide the high temperature type fuel cell device.

SOLUTION: The fuel supply system is provided with a methane density adjusting device 4 obtaining fuel gas containing hydrogen or methane component of a prescribed state by operating in reformer mode or generator mode by introducing the natural gas f1 and the gasified gas f2 with an intended ratio and adjusting temperature; and an anode supply system 6 supplying the fuel gas obtained at the methane density adjusting device 4 to a fuel electrode (anode) 3 of the high temperature type fuel cell (MCFC) 2; and made to be able to supply the fuel to the MCFC 2 regardless of the proportion of the natural gas f1 and the gasified gas f2 (in both case of using the natural gas and using the gasified gas).
