Abstract
An electrochemical cell includes a cathode including a porous scaffold and catalyst on the porous scaffold, an anode spaced apart from the cathode, a first liquid composition separated from the anode by the cathode, and a second liquid composition between the anode and the cathode, wherein the first liquid composition includes an electrolyte and a salt, the salt including a cation and a first anion, the first anion being electrochemically reduced to a second anion when flowing through the cathode, and the second liquid composition includes the electrolyte and the second anion.

An electrochemical cell, comprising:
- a cathode comprising a porous scaffold and catalyst on the porous scaffold,
- an anode spaced apart from the cathode,
- a first liquid composition separated from the anode by the cathode, and
- a second liquid composition between the anode and the cathode,
- wherein the first liquid composition comprises an electrolyte solution and a salt, the salt comprising a cation and a first anion, the first anion being electrochemically reduced to a second anion when flowing through the cathode,
- the first anion comprises peroxide (O22−), persulfate (S2O82−), hypochlorite (OCl−), chlorite (ClO2−), chlorate (ClO3−), bromite (BrO2−), bromate (BrO3−), and/or iodate (IO3−), and
- the second liquid composition comprises the electrolyte solution and the second anion.
