Membrane flow cell battery

Image Number 3 for United States Patent #5304432.

A rechargeable membrane flow cell battery useful for providing electrical power to electric loads. The rechargeable membrane flow cell battery includes a bipolar stack of at least two membrane flow cells and a single fuel cell electrode pair for converting membrane potentials generated by acidic and basic electrolyte ions to electrical potential. The ability to stack numerous membrane flow cells provides for increases in the energy density of the battery. The presence of a single electrode pair reduces activation polarization and decreases the cost and weight of the battery. Rapid recharging is accomplished by draining spent fluid and providing fresh electrolyte fluids. Conventional recharging is accomplished by reversing the fluid flows and applying electrical power, to regenerate the electrolytes.
