A redox flow battery ('CRB') performs as an energy storage system and has a negative electrode that directly utilizes COin the battery charge step as an active species instead of metals. The CRB also has a positive electrode utilizing a metallic or non-metallic redox species, and a cation exchange membrane in between the negative and positive electrodes. The negative electrode comprises a porous base layer, a porous intermediate layer containing a metal oxide and a bi-functional catalyst layer for electrochemical reduction of COor carbonate to formate and for formate oxidation to either carbonate or CO. The bi-functional catalyst can be a PdSn based catalyst, such as PdSn, PdSnIn, and PdSnPb. The metal oxide in the intermediate layer acts as a catalyst support and can be a non-Platinum group metal (PGM) oxide, such as LaCoOor LaNiO.

Carbon dioxide redox flow battery having a bi-functional negative electrode

A redox flow battery where the negative electrode uses carbon dioxide based redox couples. The negative electrode contains a bifunctional catalyst that allows for the reduction of carbon dioxide to carbonaceous species (e.g., formic acid, oxalic acid or their salts) in the battery charge (i.e., energy storage) mode, and for the oxidation of the above-mentioned carbonaceous species in the battery discharge (i.e., energy generation) mode. The positive electrode of the battery can utilize a variety of redox couples including but not restricted to bromine-bromide, chlorine-chloride, vanadium (IV)-vanadium (V), chromium (III)-dichromate (VII), cerium (III)-cerium (IV), oxygen-water (or hydroxide).

Redox flow battery with carbon dioxide based redox couple

This invention is a method and apparatus for operating electrochemical reactors with multi-phase feeds, in which a liquid feed stream is dispersed in a second fluid to form a spray, mist or emulsion before entering the reaction zone. The invention is applicable to both electro-synthesis and fuel cell reactors, with particular utility in mixed-reactant fuel cells.
