    • Alkali bicarbonate is synthesized in an electrolytic cell (100) from alkali carbonate. The electrolytic cell (100) includes an alkali ion conductive membrane (110) positioned between an anolyte compartment (112) configured with an anode (116) and a catholyte compartment (114) configured with a cathode (118). The alkali conductive membrane (110) selectively transports alkali ions (120) and prevents the transport of anions produced in the catholyte compartment. An aqueous alkali carbonate solution is introduced into the anolyte compartment (112) and electrolyzed at the anode (116) to produce carbon dioxide and/or hydrogen ions which react with alkali carbonate to produce alkali bicarbonate. The alkali bicarbonate is recovered by filtration or other separation techniques. When the catholyte solution includes water, pure alkali hydroxide is produced. When the catholyte solution includes methanol, pure alkali methoxide is produced.

    • A scaffold (10) holding one or more ion-conductive ceramic membranes (25) for use in an electrochemical cell is described. Generally, the scaffold (10) includes a thermoplastic plate (20) defining one or more orifices (15). Each orifice (15) is typically defined by a first, second, and third aperture, wherein the second aperture is disposed between the first and third apertures. The diameter of the second aperture can be larger than the diameters of the first and third apertures. While at an operating temperature the diameter of the ceramic membrane (25) is larger than the diameters of the first and third apertures, heating the scaffold (10) to a sufficient temperature and for a sufficient time causes the third aperture's diameter to become larger than the membrane's diameter. Thus, heating the scaffold (10) may allow the membrane to be inserted into the orifice (15). Cooling the scaffold (10) can then cause the third aperture's diameter to shrink and trap the membrane (25) within the orifice (10).
    • 描述了用于电化学电池中的保持一个或多个离子导电陶瓷膜(25)的支架(10)。 通常,支架(10)包括限定一个或多个孔(15)的热塑性板(20)。 每个孔(15)通常由第一,第二和第三孔限定,其中第二孔设置在第一和第三孔之间。 第二孔的直径可以大于第一和第三孔的直径。 在工作温度下,陶瓷膜(25)的直径大于第一和第三孔的直径,将支架(10)加热至足够的温度并持续足够的时间使得第三孔的直径变得比 膜的直径。 因此,加热支架(10)可允许膜插入孔口(15)中。 然后冷却支架(10)可以使第三孔的直径收缩并将膜(25)捕获在孔口(10)内。
