    摘要： A process can be used for electrochemical preparation of an alkali metal alkoxide solution. The process is performed in an electrolysis cell having three chambers, where 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 process solves a problem where a concentration gradient forms in the middle chamber of the electrolysis cell during the electrolysis, which leads to locally lowered pH values and damage to the solid-state electrolyte used. This is prevented where a gas is introduced into the middle chamber during the electrolysis, which results in better mixing of the electrolyte solution in the middle chamber and prevents the formation of a concentration gradient.

    摘要： Systems and methods of enhancing oil recovery with an electrochemical apparatus include introducing the electrochemical apparatus into an injection well bore. The electrochemical apparatus includes an anode, a cathode and an interior wall, the interior wall defining an interior that contains both the anode and the cathode. The electrochemical apparatus is operated such that injection water of the injection well bore is introduced into the interior of the electrochemical apparatus. Electrical power is introduced to the electrochemical apparatus such that a portion of the injection water is converted into a product gas, the product gas including hydrogen gas and oxygen gas. The electrochemical apparatus is operated such that the product gas forms product gas bubbles and the product gas bubbles travel into a formation, where the product gas bubbles react with a reservoir hydrocarbon of the formation to form a production fluid that is produced through a production well bore.

    摘要： An electrolytic solution generator includes an electrolyzing unit having a stacked structure in which a conductive film is interpose between a cathode and an anode, the electrolyzing unit electrolyzing a liquid, and a housing in which the electrolyzing unit is placed. A channel is disposed in the housing, and a groove is disposed in the electrolyzing unit, as a groove which is open to the channel and to which at least a part of an interface between the conductive film and the cathode and an interface between the conductive film and the anode is exposed. A space is disposed between at least either an outer periphery of the cathode or an outer periphery of the anode and an inner surface of the housing.

    摘要： The invention relates to a distribution structure (10) for providing at least one reaction gas, in particular a gas mixture containing oxygen (O2), for a fuel cell (100) or an electrolyser, having a first structure element (11) and a second structure element (12), wherein the first structure element (11) and the second structure element (12) are designed and arranged with respect to one another such that: a distribution area (15) for the reaction gas is formed between the first structure element (11) and the second structure element (12); a plurality of feed channels (16) branch off from the distribution area (15) and are orientated substantially perpendicular to the distribution area (15); and a plurality of discharge channels (17) are formed below the second structure element (12) and are orientated parallel to the distribution area (15).
