Abstract: Systems and methods are provided for a rebalancing cell for a redox flow battery. In one example, the rebalancing cell may include a stack of electrode assemblies, wherein each electrode assembly may include a negative electrode interfacing with a flow field plate for inducing flow of H2 gas from the redox flow battery. In some examples, each electrode assembly may further include a positive electrode formed from a wicking carbon felt for inducing flow of an electrolyte from the redox flow battery. In some examples, no electric current may be directed away from the rebalancing cell and the negative and positive electrodes of each electrode assembly may be continuously electrically conductive. In this way, each electrode assembly of the rebalancing cell may be internally shorted, thereby increasing reduction rates of the rebalancing cell without sacrificing overall reliability.

Abstract: Hybrid catalyst suitable for use in a proton exchange membrane fuel cell and method of preparing same. In one embodiment, the hybrid catalyst is iron-free and includes an Mn- N-C support and platinum-containing nanoparticles that are dispersed on the Mn-N-C support. The Mn-N-C support preferably comprises atomically dispersed and nitrogen coordinated MnN4 moieties and has a particle size of about 30 to 200 nm. The platinum-containing nanoparticles preferably have a particle size ranging from about 2 to 8 nm and are made of platinum or a platinum-cobalt intermetallic alloy, such as a cubic L12 Pt3Co alloy or a tetragonal L10 PtCo alloy. The hybrid catalyst may be made by combining a quantity of a hexachloroplatinic acid solution with a quantity of an Mn-N-C support, sonicating the mixture in an ice bath, freeze-drying the sonicated product, calcinating the freeze-dried product under a forming gas, and heating the calcinated product.
