A reactor and process capable of concurrently producing electric power and selectively oxidizing gaseous components in a feed stream, such as hydrocarbons to unsaturated products, which are useful intermediates in the production of liquid fuels. The reactor includes an oxidation membrane, a reduction membrane, an electron barrier, and a conductor. The oxidation membrane and reduction membrane include an MIEC oxide. The electron barrier, located between the oxidation membrane and the reduction membrane, is configured to allow transmission of oxygen anions from the reduction membrane to the oxidation membrane and resist transmission of electrons from the oxidation membrane to the reduction membrane. The conductor conducts electrons from the oxidation membrane to the reduction membrane.
