摘要： This invention relates to a device for the electrolytic production of hydrogen and oxygen from a water-containing liquid, the device comprising: an anodic half-cell (3) and a cathodic half-cell (4), with an anion exchange membrane (9) situated between the two half-cells. The electrodes (7, 8) of the half-cells (3, 4) and the anion exchange membrane (9) form a membrane/electrode assembly (MEA). There is also provided means (2) for feeding the water-containing liquid to only one of the anodic half-cell (3) and the cathodic half-cell (4), wherein the electrode in the other, substantially dry, half-cell is ionomer-free and/or binder-free.

摘要： An exchange membrane includes, for example, a first layer membrane having a first thickness, a second layer membrane having a thickness less than the first thickness, and the second layer membrane containing a catalyst, a catalyst content in the second layer membrane being greater than a catalyst content in the first layer membrane, and the exchange membrane having an interface between the first layer membrane and the second layer membrane. In some embodiments, the membrane electrode assembly (MEA) includes the first layer membrane without a catalyst, and/or the exchange membrane includes a bi-layer exchange membrane.

摘要： An electrochemical process is provided for producing hydrogen for use in a hydrotreatment process. Hydrogen sulfide and ammonia that are produced during the hydrotreatment process are subjected to electrolysis using electrolysis cells and select catalysts to produce hydrogen which then can be used in the hydrotreatment process instead of using outside sources of hydrogen.

摘要： A method of hydrogenating carbon dioxide comprises forming a tunable catalyst comprising at least one metal comprising a size within a range of from a single atom to about 999 nanometers and formulated to produce one or more carbon-containing compound. An electrochemical cell comprising a positive electrode, a negative electrode comprising the tunable catalyst, and an electrolyte between the positive electrode and the negative electrode is formed. Carbon dioxide is introduced to the negative electrode of the electrochemical cell and a potential difference is applied between the positive electrode and the negative electrode to selectively hydrogenate the carbon dioxide. The hydrogen ions are diffused through the electrochemical cell. The carbon dioxide at the negative electrode is hydrogenated to selectively form carbon monoxide, methane, or a desired ratio of carbon monoxide and methane. An electrochemical cell and a carbon dioxide hydrogenation system are also disclosed.
