Flow battery start-up and recovery management

摘要

A start-up plating process for a flow cell battery is disclosed. Upon start-up of the flow-cell stack, catalysts may have deplated from the electrodes. The catalyst is replated to the electrode by application of currents to the stack prior to circulating electrolyte fluids.

1. A method of performing a start-up of a flow cell system, wherein electrolyte is flowed through cells in a stack of the flow cell system with circulation pumps, comprising:
performing a static plating by applying a current to a stack of the flow cell system with the circulation pumps turned off to plate a catalyst dissolved in the electrolyte onto electrodes of the cells in the stack; turning circulation pumps on once the static plating step is completed to flow electrolyte through the stack of the flow cell system.
