A Flow Cell System that utilizes a Vanadium Chemistry is provided. The flow cell system includes a stack, electrolyte heat exchangers, and a controller executing a state machine.

Vanadium flow cell

A stacked cell for a flow cell battery is presented. The stacked cell is sealed by a gasket between individual components. The gasket is formed such that it seals against leakage of electrolytes and facilitates the flow of electrolytes through the stacked cell. Further, the gasket is formed to minimize the linear expansion of the gasket material with temperature.

Flow cell stack

A method for bonding a porous flexible membrane to a rigid material is disclosed. In some embodiments, the method includes applying, at a bonding site of the porous membrane, a pre-treatment solvent solution, drying the bonding site of the porous membrane, applying, at a bonding site of the rigid structure, a first solvent that is capable of dissolving a surface of the rigid material, applying, at the bonding site of the porous membrane, a second solvent that is capable of dissolving the polymeric residue material dissolved in the pre-treatment solvent solution, and pressing the porous membrane to the rigid material at their respective bonding sites. In some embodiments, the pre-treatment solvent solution may include a solvent carrying dissolved polymeric residue material configured to fill the pores of the porous membrane at the bonding site of the porous membrane.

Methods for bonding porous flexible membranes using solvent

A redox cell rebalance system is provided. In some embodiments, the rebalance system includes electrochemical cell and a photochemical cell. In some embodiments, the photochemical cell contains a source of ultraviolet radiation for producing HCl from Hand Clgenerated by the system. The HCl product may be collected or circulated back through the system for the rebalancing of electrolytes. A rebalance cell for use in a rebalance system is also provided. In some embodiments, the rebalance cell is the combination of an electrochemical cell and a photochemical cell. In some embodiments, a source of ultraviolet radiation is housed in the cathode compartment of the rebalance cell. In some embodiments, the source of ultraviolet radiation is used to effect the formation of HCl from Hand Clpresent in the rebalance cell. The HCl is dissolved in aqueous electrolytes contained in the rebalance cell, which can subsequently be circulated through a rebalance system for the rebalancing of redox cells.

Redox flow cell rebalancing

A method of producing HCl from Hand Clis provided. In some embodiments, the method comprises at least one photochemical chamber placed in fluid communication with at least one source of Hand at least one source of Cl. In some embodiments, the photochemical chamber effects the formation of HCl through the use of at least one source of ultraviolet radiation contained therein. In some embodiments, the HCl product may be captured and used as a gas. In some embodiments, the HCl product may be absorbed into water to form an aqueous HCl solution.

Methods of producing hydrochloric acid from hydrogen gas and chlorine gas

An electrode for use in a flow cell is presented. The electrode includes a metal plate for collecting current in the electrode that is bonded between a first and second plate.
