A platform technology that uses a novel membrane electrode assembly including a cathode layer comprising a reduction catalyst and a first anion-and-cation-conducting polymer, an anode layer comprising an oxidation catalyst and a cation-conducting polymer, a membrane layer comprising a cation-conducting polymer, the membrane layer arranged between the cathode layer and the anode layer and conductively connecting the cathode layer and the anode layer, in a COreduction reactor has been developed. The reactor can be used to synthesize a broad range of carbon-based compounds from carbon dioxide.

Reactor with advanced architecture for the electrochemical reaction of CO, CO, and other chemical compounds

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

Provided herein are membrane electrode assemblies (MEAs) for COreduction and carbon dioxide reduction reactors (CRRs) that include MEAs.

Membrane electrode assembly for COreduction

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

A platform technology that uses a novel membrane electrode assembly, including a cathode layer, an anode layer, a membrane layer arranged between the cathode layer and the anode layer, the membrane conductively connecting the cathode layer and the anode layer, in a COreduction reactor has been developed. The reactor can be used to synthesize a broad range of carbon-based compounds from carbon dioxide and other gases containing carbon.

Reactor with advanced architecture for the electrochemical reaction of CO, co and other chemical compounds

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

A method of forming a gas diffusion layer includes causing, at least in part, a stack of layers to be arranged between compressing surfaces of a press, the stack of layers including a plurality of gas diffusion layers. The method also includes causing, at least in part, the press to apply one or more compression cycles to the stack of layers to reduce a combined, uncompressed thickness of the plurality of gas diffusion layers between about 2% and about 30%.

COx electrolyzer cell flow fields and gas diffusion layers

Disclosed are membrane electrode assemblies having a cathode layer comprising a carbon oxide reduction catalyst that promotes reduction of a carbon oxide; an anode layer comprising a catalyst that promotes oxidation of a water; a polymer electrolyte membrane (PEM) layer disposed between, and in contact with, the cathode layer and the anode layer; and a salt having a concentration of at least about 10 uM in at least a portion of the MEA.

Electrolyzer and method of use
