摘要： The present invention relates, in a first aspect, to an electrolysis cell E comprising a dividing wall W suitable for use in an electrolysis cell E. The dividing wall W encompasses at least two alkali metal cation-conducting solid-state electrolyte ceramics FA and FB separated from one another by at least one separating element T. Compared to the cases according to the prior art in which the dividing wall W encompasses the solid-state electrolyte in one piece, this arrangement is more flexible and the individual ceramics have more degrees of freedom available in order to react to fluctuations in temperature, for example by shrinkage or expansion. This increases stability with respect to mechanical stresses in the ceramic.
The electrolysis cell E encompasses a cathode chamber KK divided by the dividing wall W from the adjacent chamber, which is a middle chamber KM of the electrolysis cell E.
In a second aspect, the present invention relates to a process for producing an alkali metal alkoxide solution in the electrolysis cell E according to the first aspect of the invention.

摘要： 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.

摘要： The present invention relates, in a first aspect, to an electrolysis cell having three chambers, wherein the middle chamber is separated from the cathode chamber by a solid-state electrolyte permeable to cations, for example NaSICON, and from the anode chamber by a diffusion barrier, for example a membrane selective for cations or anions. The invention is characterized in that the middle chamber comprises a mechanical stirring device.
The electrolysis cell according to the invention solves the problem that a concentration gradient forms in the middle chamber of the electrolysis cell during the electrolysis, which leads to locally lowered pH values and hence to damage to the solid-state electrolyte. With the aid of the mechanical stirring device, it is possible to stir the electrolyte solution in the middle chamber during the electrolysis. This leads to mixing of the electrolyte solution in the middle chamber, which prevents the formation of a pH gradient.
In a second aspect, the present invention relates to a process for producing an alkali metal alkoxide solution in the electrolysis cell according to the invention.

摘要： An energy conversion system includes a fuel synthesis device, an H2O supply unit, a CO2 supply unit, and a supply control unit. The fuel synthesis device includes an electrolyte, and a pair of electrodes provided on both sides of the electrolyte. The H2O supply unit supplies H2O to the fuel synthesis device. The CO2 supply unit supplies CO2 to the fuel synthesis device. The supply control unit controls a supply of H2O and a supply of CO2. The fuel synthesis device electrolyzes H2O and CO2 using external electric power, and synthesizes a hydrocarbon using H2 and CO generated by electrolysis. The supply control unit starts the supply of H2O to the fuel synthesis device by the H2O supply unit after the supply of CO2 to the fuel synthesis device by the CO2 supply unit is started.
