Abstract
A flow battery system is provided that has at least one cell stack and at least a pair of storage containers or tanks connected to the at least one cell stack. Each of the storage containers is formed from a rigid (e.g., metal) shell and includes a liner directly bonded to inner walls of the rigid shell and forming an enclosure configured to retain a liquid electrolyte. The electrolyte can be an anolyte or catholyte. In the assembled configuration, the metal shell of the storage container provides secondary containment whereas the liner directly bonded thereto provides primary containment. The flow battery system includes a fault detection system configured to detect a presence of a fault or leak and further to determine a location of that leak in the flow battery system, such as a storage container or a specific portion of the storage container.
