A flow battery system includes a first tank including a hydrogen reactant, a second tank including a bromine electrolyte, and at least one cell including a first electrolyte side operably connected to the first tank and a second electrolyte side operably connected to the second tank. The battery system further includes a direct connection line directly connecting the first tank and the second tank and configured such that the hydrogen reactant passes between the first tank and the second tank.

Hydrogen/bromine flow battery in which hydrogen is freely exchanged between two cell compartments

A flow battery system and method of operating the system minimizes performance losses. The flow battery system includes at least one cell, a first tank including a liquid electrolyte, a pump operably connected to the first tank and to the at least one cell, and a second electrolyte tank operably connected to the at least one cell. The flow battery system further includes a memory including program instructions stored therein, at least one sensor configured to a generate at least one signal associated with a sensed condition of the battery system, and a controller operably connected to the at least one sensor, the pump, and the memory and configured to execute the program instructions to determine a dead zone condition exists based upon the at least one signal, and control the pump to pulse flow of the liquid electrolyte to the at least one cell based upon the determination.

System and method for minimizing transport related performance losses in a flow battery system

A flow battery system includes a first tank having a hydrogen reactant, a second tank having a bromine electrolyte, at least one cell including a hydrogen reactant side operably connected to the first tank through an &#xbe; feed and return system and a bromine electrolyte side operably connected to the second tank, and a crossover return system. The crossover return system includes a vessel operably connected to the &#xbe; feed and return system and configured to receive an effluent containing a first portion of the hydrogen reactant and a second portion of the bromine electrolyte, the vessel configured to separate the first portion from the second portion. A first return line returns the first portion of the hydrogen reactant to the first tank and a second return line returns the bromine electrolyte to the second tank.
