    Abstract: The present invention relates to an undivided electrochemical cell for ferrate(V) and/or ferrate(VI) continuous production, comprising:
    a housing defining an undivided chamber, the housing having one electrolyte inlet;
    an iron-containing anode in the chamber;
    a cathode in the chamber;
    an electrolyte in the chamber,
    a screen between the anode and the cathode in the chamber, defining an anode compartment and a cathode compartment;
    at least two outlets, one for the anode compartment and one for the cathode compartment; and
    a variable direct current power supply operatively connected to electrochemical cell; wherein the direct current power supply is capable of producing a continuously and automatically varied variable direct current voltage between the anode and the cathode to form the ferrate(V) and/or ferrate(VI), the variable direct current voltage varying between a maximum voltage (Vmax) and a minimum voltage (Vmin), the Vmin is greater than 0 and is a voltage to ensure that formation of an oxide film on a surface of the anode is depressed so that passivation of the anode is substantially avoided;
    wherein the anode is not a gas diffusion electrode, and
    wherein the anode and cathode are substantially vertical.

    Abstract translation: 本发明涉及一种用于高铁酸盐（V）和/或高铁酸盐（VI）连续生产的不分开的电化学电池，包括：限定不分隔室的壳体，所述壳体具有一个电解质入口; 室内的含铁阳极; 腔室中的阴极; 室中的电解质，室中的阳极和阴极之间的屏幕，限定阳极室和阴极室; 至少两个出口，一个用于阳极室，一个用于阴极室; 以及可操作地连接到电化学电池的可变直流电源; 其中所述直流电源能够在所述阳极和所述阴极之间产生连续且自动变化的可变直流电压，以形成所述高铁酸盐（V）和/或高铁酸盐（VI），所述可变直流电压在最大电压 （Vmax）和最小电压（Vmin），Vmin大于0，并且是确保在阳极表面上形成氧化膜的电压，从而基本上避免了阳极的钝化; 其中所述阳极不是气体扩散电极，并且其中所述阳极和阴极基本上是垂直的。
