요약

A system and method in which a high temperature fuel cell stack exhaust stream is recycled back into the fuel inlet stream of the high temperature fuel cell stack. The recycled stream may be sent to a carbon dioxide separator that separates carbon dioxide from the fuel exhaust stream. The carbon dioxide separator may include a carbon dioxide separation membrane, an oxygen blocking membrane, and a water blocking membrane.

대표청구항

1. A carbon dioxide separator for a fuel cell system, the carbon dioxide separator comprising: a sweep channel configured to receive a sweep gas;a feed channel configured to receive a fuel exhaust stream of the fuel cell system;a carbon dioxide separation membrane disposed between the sweep channel and the feed channel, the carbon dioxide separation membrane having a higher permeability to carbon dioxide and water than to hydrogen gas, carbon monoxide, and nitrogen gas; anda first blocking layer disposed on a first side of the carbon dioxide separation membrane and comprising a first oxygen blocking layer disposed between the carbon dioxide separation membrane and the sweep channel, the oxygen blocking layer having a higher permeability to water and carbon dioxide than to oxygen gas and nitrogen gas.
