    摘要： The present invention generally relates to cathodes used to produce chlorine gas from gaseous hydrogen chloride. The cathode comprises a cathode electrolyte comprising Fe(II) compounds and Fe(III) compounds in contact with an electron conductor. A reactor comprises a reactor solution comprising an oxidant in fluid contact with the cathode electrolyte. The fluid contact of the reactor solution with the cathode electrolyte allows the cathode electrolyte rich in Fe(II) compounds to be transferred to the reactor and combined with the reactor solution and the reactor solution rich in Fe(III) compounds to be transferred from the reactor to the cathode electrolyte after the oxidant of the reactor solution reacts with the electrolyte rich in Fe(II) compounds to form the reactor solution rich in Fe(III) compounds.

    摘要： A novel design has been invented for redox flow batteries. Different from the single-membrane, double-electrolyte redox flow battery as a basic structure, the design of the present invention involves double-membrane (one cation exchange membrane and one anion exchange membrane), triple-electrolyte (one electrolyte in contact with the negative electrode, one electrolyte in contact with the positive electrode, and one electrolyte positioned between and in contact with the two membranes) as the basic characteristic. The cation exchange membrane is used to separate the negative or positive electrolyte and the middle electrolyte, and the anion exchange membrane is used to separate the middle electrolyte and the positive or negative electrolyte. This particular design physically isolates, but ionically connects, the negative electrolyte and positive electrolyte. The physical isolation offers a great freedom in choosing redox pairs in the negative electrolyte and positive electrolyte, making high voltage of redox flow batteries possible. The ionic conduction not only makes the design functional, but also drastically reduces the overall ionic crossover between negative electrolyte and positive one, leading to high columbic efficiency.

    摘要翻译： 氧化还原电池已经发明了一种新颖的设计。 与单膜双电解质氧化还原液流电池作为基本结构不同，本发明的设计涉及双膜（一阳离子交换膜和一阴离子交换膜），三电解质（一电解质与 负极，与正极接触的一个电解质，以及位于两个膜之间并与两个膜接触的一个电解质）作为基本特征。 阳离子交换膜用于分离阴性或正电解质和中间电解质，阴离子交换膜用于分离中间电解质和正电解质或负电解质。 这种特殊的设计将负电解质和正电解质物理隔离，但是离子连接。 物理隔离在负电解质和正电解质中选择氧化还原对有很大的自由度，可以使氧化还原液电池达到高电压。 离子传导不仅使设计功能化，而且大大降低了负电解质和正电解质之间的总体离子交换，从而导致高的串联效率。
