GAS CIRCULATION TYPE SOLID OXIDE FUEL CELL/WATER VAPOR ELECTROLYSIS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell/water vapor electrolysis system which converts electric energy and hydrogen with high efficiency.SOLUTION: A solid oxide fuel cell/water vapor electrolysis system 1 comprises: a solid oxide fuel cell 10 which performs a power generating operation for producing electric energy using a hydrogen gas as a fuel and an electrolysis operation for producing a hydrogen gas from water vapor and electric energy; a storage device 11 for storing the hydrogen gas and the water vapor to be supplied to the solid oxide fuel cell 10; and conduction piping 12 that connects the solid oxide fuel cell 10 and the storage device 11. The solid oxide fuel cell/water vapor electrolysis system further comprises a blower 14 which is provided in the middle of a path of the conduction piping 12 and circulates the hydrogen gas and the water vapor between the solid oxide fuel cell 10 and the storage device 11 in such a manner that an exhaust gas exhausted from the solid oxide fuel cell 10 is inputted to the storage device 11 and that a fuel gas supplied from the storage device 11 is inputted to the solid oxide fuel cell 10.SELECTED DRAWING: Figure 1
