The solid oxide fuel cell power generation system for one-piece heat exchanger

The present invention is supplied to the stack by using the gas that is intended to provide a one-piece heat exchanger for a catalytic combustor, and a plurality of flat-type heat exchanger consisting of small solid oxide fuel cell (solid oxide fuel cell, SOFC) power generation system, the exhaust from the SOFC stack, in order to preheat the air and fuel to produce steam, is mounted in the lower part of the SOFC stack, the gas discharged from the SOFC stack in the integrated heat exchange apparatus is characterized in that the flow cross-sectional area without a change in fluid flow. SOFC, stacks, heat exchangers, catalytic combustor, plate-like, off-gas, pre-heating, power generation system
