Abstract
Provided herein are CO-selective membranes that can be used to efficiently separate COand CO. The membranes can be used to produce high-purity COand CO gas streams from a feed gas stream comprising a mixture of COand CO (e.g., an exhaust gas stream from a fuel cell, such as a solid oxide fuel cell). In this way, the membranes can be used with a solid oxide fuel cell system to covert COto CO.
