Patent Searching and Data


Title:
Soundness evaluation method, equipment and program of fuel gas flow path of solid oxide fuel cell
Document Type and Number:
Japanese Patent JP6284814
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of estimating the soundness of a fuel gas passage of a solid oxide type fuel battery.SOLUTION: Methane containing no water vapor is analyzed by a gas chromatograph, methane-contained gas and water vapor are mixed to prepare reaction gas, the reaction gas is supplied to a fuel gas introducing portion of a fuel electrode containing a fuel gas passage of SOFC to exhaust off-gas from a fuel gas exhaust portion of the fuel electrode containing the fuel gas passage, water vapor is removed from the off-gas to prepare analysis off-gas, the component amount of the analysis off-gas is analyzed by the gas chromatograph, the component amount of the reaction gas is calculated from the component amount of the methane-contained gas and the water vapor containing percentage of the reaction gas, mass balance calculation is executed in consideration of a chemical reaction occurring at the fuel electrode containing the fuel gas passage by using the component amount of the reaction gas and the component amount of the analysis off-gas to calculate the component amount of the off-gas, and the reaction condition of methane at the fuel electrode containing the fuel gas passage is grasped by using the component amount of the reaction gas and the component amount of the off-gas.
