Abstract
A method of rebalancing electrolytes in a redox flow battery system comprises directing hydrogen gas generated on the negative side of the redox flow battery system to a catalyst surface, and fluidly contacting the hydrogen gas with an electrolyte comprising a metal ion at the catalyst surface, wherein the metal ion is chemically reduced by the hydrogen gas at the catalyst surface, and a state of charge of the electrolyte and pH of the electrolyte remain substantially balanced.

A redox flow battery, comprising:
- a redox flow battery cell, and
- a catalyst bed positioned in a rebalancing reactor fluidly coupled to the redox flow battery cell, the catalyst bed including,
- a substrate layer, a spacing layer, and a catalyst layer interposed between and attached to the substrate layer and the spacing layer to form a one-piece removable catalyst bed.
