SEALING DEVICE FOR SOLID OXIDE FUEL CELL

摘要

The present invention relates to a sealing device which seals both ends of a solid oxide fuel cell stack, the device comprising: a gas inlet in which fuel gas is injected; a gas buffer unit which disperses and supplies the fuel gas injected from the gas inlet to a plurality of gas supply pipes formed on the inside of the fuel cell stack; and a first sealing unit, a second sealing unit, and a third sealing unit which seal an end part of the fuel cell stack as a stepwise space expanded and connected to the gas buffer unit. By providing a space which seals the fuel cell stack in three stages, and buffers and disperses the fuel gas, the fuel gas is smoothly supplied to the inside of the fuel cell stack without leakage.
