Abstract
A redox flow battery includes a flow field having ribs that define inlet channels interdigitated with outlet channels. A first rib is flush with a reference plane and a second rib is also provided that is shorter in height than the first rib. The second rib borders each of the inlet channels and each of outlet channels and an electrolyte over-rib-flow space is defined between a top surface of the second rib and the reference plane.
Claims17
A redox flow battery comprising:
- a first flow field including ribs that define inlet channels interdigitated with outlet channels, the ribs including a first rib and a second rib, the first rib having a first rib height and the second rib having a second rib height that is less than the first rib height;
- and
- the second rib bordering one of the inlet channels and one of the outlet channels such that an electrolyte over-rib-flow space is defined between a top surface of the second rib and a reference plane, the reference plane being flush with a top surface of the first rib.
