摘要： Apparatuses and methods for performing coupled chemical and electrochemical reactions are disclosed. An electrochemical cell has a first reaction chamber configured to perform a chemical reaction and an anode chamber configured to perform an electrochemical reaction. The first reaction chamber and the anode chamber are separated by a first membrane. The first membrane acts as a cathode of the cell, a hydrogen-selective layer and a catalyst. The first membrane may comprise a layer of palladium or a palladium alloy. An ion exchange membrane separates the first membrane and the anode chamber. The chemical and electrochemical reactions may respectively be hydrogenation and dehydrogenation reactions.

摘要： Apparatuses and methods for producing hydrogen peroxide by performing coupled chemical and electrochemical reactions are disclosed. An electrochemical cell has a chemical reaction chamber configured to hydrogenate a shuttle molecule and an electrochemical chamber configured to electrochemically dissociate water to form hydrogen ions at an anode, and to reduce the hydrogen ions to atomic hydrogen at a cathode. The chemical reaction chamber and the anode chamber are separated by a metallic membrane. The metallic membrane acts as a cathode of the cell, a hydrogen-selective layer and a catalyst. The metallic membrane may comprise a layer of palladium or a palladium alloy. A layer of co-catalyst may optionally be electrodeposited on the layer of palladium or palladium alloy. An ion exchange membrane separates the metallic membrane and the anode chamber. The hydrogenated shuttle molecule may be supplied to a reactor for contacting an oxygen-containing gas to yield hydrogen peroxide.

摘要： An apparatus and method for sourcing nuclear fusion products uses an electrochemical loading process to load low-kinetic-energy (low-k) light element particles into a target electrode, which comprises a light-element-absorbing material (e.g., Palladium). An electrolyte solution containing the low-k light element particles is maintained in contact with a backside surface of the target electrode while a bias voltage is applied between the target electrode and an electrochemical anode, thereby causing low-k light element particles to diffuse from the backside surface to an opposing frontside surface of the target electrode. High-kinetic-energy (high-k) light element particles are directed against the frontside, thereby causing fusion reactions each time a high-k light element particle operably collides with a low-k light element particle disposed on the frontside surface. Fusion reaction rates are controlled by adjusting the bias voltage.

摘要： Processes and apparatus for electrocatalytically converting carbon dioxide emissions and/or ambient carbon dioxide into useful chemicals are described. The process may include: removing carbon dioxide from ambient air through a carbon capture technique, supplying a carbonate or bicarbonate aqueous solution as cathode feed to a cathode of an electrolytic cell comprising a membrane electrode assembly which includes a bipolar membrane separating an anode from the cathode, and applying an electrical potential difference between the cathode and the anode of the membrane electrode assembly to electrocatalytically reduce the carbonate or bicarbonate aqueous solution to carbon monoxide or another useful chemical.
