Title:
RECYCLE AND REUSE METHOD OF FUEL ELECTRODE EXHAUST GAS IN SOLID OXIDE FUEL CELL
Document Type and Number:
Japanese Patent JP2015043263
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a recycle and reuse method of a fuel electrode exhaust gas in a SOFC capable of increasing drive gas flow rate in an ejector to improve the efficiency at the power generation end, while solving a problem of decrease in reforming performance due to circulation of a SOFC fuel electrode exhaust gas.SOLUTION: A part of a fuel electrode exhaust gas is circulated to a fuel supply system to a fuel cell (1) to reuse un-combusted fuel gas which is capable of generating the power contained in a fuel electrode exhaust gas discharged from a SOFC (1). An ejector (4) is provided to a fuel gas supply line (3) between a reformer (2) which vapor-reforms raw fuel into a fuel gas and the fuel cell (1) and a fuel electrode exhaust gas circulation line (5) from the fuel cell (1) is connected to the fuel gas supply line (3). The ejector (4) is driven by the fuel gas which is output from the reformer (2) and the fuel electrode exhaust gas is sucked by the ejector (4).
