Abstract

Provided herein are membrane electrode assemblies (MEAs) for COx reduction. According to various embodiments, the MEAs are configured to address challenges particular to COx including managing water in the MEA. Bipolar and anion-exchange membrane (AEM)-only MEAs are described along with components thereof and related methods of fabrication.
