Abstract: A system and method for generating arsine are disclosed. The system may include a shell having a top interior surface. The system may also include a cathode-anode assembly positioned in the shell and forming an elongated structure substantially parallel to the top surface. The cathode-anode assembly may include a first electrode and a second electrode surrounding the first electrode and forming a gap therebetween. The second electrode may include a plurality of channels along a length of the second electrode. The plurality of channels may allow circulation of electrolyte within and around at least a portion of the cathode-anode assembly and allow gases generated in response to current applied to the cathode-anode assembly to escape from the cathode-anode assembly. Such gases may be used as precursor gases for a high-volume metal-organic chemical vapor deposition (MOCVD) operation.

Abstract: An embodiment of the present invention provides a catalyst with maximized activity and stability through synthesizing carbon quantum dots with transition metal elements introduced based on carbon compound monomers containing nitrogen elements that have excellent bonding ability with transition metals. By introducing low-cost transition metal atoms into nano carbon quantum dots (CQDs), a type of highly stable carbon nanostructure, the activity and stability of the hydrogen generation catalyst reaction through water electrolysis are simultaneously increased, so that an economical, highly active, highly stable catalyst for electrochemical hydrogen generation reaction can be manufactured.

Abstract: Provided herein are systems and methods for operating carbon oxide (COx) reduction reactors (CRRs) for producing methane (CH4). 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 (CH2CH2). 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.

Abstract: Methods of preparing cell element(s) that are operable in alkaline or anion exchange electrochemical devices are provided, as well as corresponding cell elements and electrochemical devices such as fuel cells, electrolyzers and reversible dual devices. Binder material is mixed with catalyst material and optionally ionomer material, and coated on support layer(s) and/or one or both side of a membrane, and the catalyst layers are hot-pressed briefly, to improve the adhesion of the layer and its cohesivity. Membrane electrode assemblies are prepared from the cell elements in various configurations of the catalyst layers with respect to the cell elements, and the added binder and hot pressing improve the long-term performance and durability of the electrochemical devices.
