<p>A solid-state hydroxide (OH-) conductive membrane (210) provides up to five times higher ionic conductivity and surface oxygen exchange rate than conventional MIEC membranes (110), while operating at significantly lower temperatures and providing reduced overall system cost. The hydroxide conductive membrane (210) utilizes a porous ceramic backbone (236), pores (238) of which are injected with an electrolyte (242). A catalyst (234, 232) is provided as discrete layers disposed at the anode (214) and cathode (212). The membrane (210) of the present invention may be utilized in combination with an external voltage source to drive the oxygen generating reaction. Alternatively, the pores may be metallized (240) and a pressure gradient utilized to drive the reaction. The membrane (210) thus provides discrete materials to provide ionic conduction, electronic conduction, and structural support.</p> |
