The present disclosure relates to compositions including a first polymeric structure having a structure of Formula (I), (II), (III), (IV), or (V): or a salt thereof, and a second polymeric structure having a structure of Formula (X) or Formula (XI): or a salt thereof, in which at least one of these can include an ionizable moiety or an ionic moiety, for use in an electrochemical cell. Materials, devices, and methods using such compositions are also described.

Ionic polymers and copolymers

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

Membrane electrode assembly for COx reduction

A system optionally including a carbon oxide reactor. A method for carbon oxide reactor control, optionally including selecting carbon oxide reactor aspects based on a desired output composition, running a carbon oxide reactor under controlled process conditions to produce a desired output composition, and/or altering the process conditions to alter the output composition.

System and method for carbon dioxide reactor control

Provided herein are systems and methods for operating carbon oxide (CO) reduction reactors (CRRs) for producing methane (CH). Embodiments of the systems and methods may also be used for producing other organic compounds including alcohols, carboxylic acids, and other hydrocarbons such as ethylene (CHCH). According to various embodiments, the systems and methods may be characterized by one or more of the following features. In some embodiments, a membrane electrode assembly (MEA) includes a cathode catalyst layer with a relatively low catalyst loading. In some embodiments, a bipolar MEA includes a thin cation-conducting layer and a thin anion-conducting layer, with the cation-conducting layer being thicker than the anion-conducting layer. In other embodiments a pure anion exchange polymer only membrane may be used to bridge the cathode catalyst and the anode catalyst. These and other features are described further below.

System and method for methane production

Provided are compositions including a core moiety and a plurality of polymeric units, in which at least one of these can include an ionizable moiety or an ionic moiety. The core moiety may be a multivalent core moiety, trivalent core moiety, tetravalent core moiety, pentavalent core moiety, or multivalent arylene moiety. Materials, electrochemical cells, and methods using such compositions are also described.

Semi-interpenetrating and crosslinked polymers and membranes thereof

Provided herein are methods for operating carbon oxide (CO) reduction reactors (CRR) and related apparatus. In some embodiments, the methods involve shutting off, reducing, or otherwise controlling current during various operation stages including hydration, break-in, normal operation, planned shut-offs, and extended shutoff or storage periods.
