1. An electrical power system, comprising:
an electric energy storage cell including a positive reactor, a negative reactor, a barrier providing fluidic isolation between the positive reactor and the negative reactor, a first portion of a first electrolyte, and a first portion of a second electrolyte that is not in fluidic communication with the first electrolyte;
a first fluidic passage housing a second portion of the first electrolyte that is in fluidic communication with the positive reactor;
a second fluidic passage housing a second portion of the second electrolyte that is in fluidic communication with the negative reactor;
a metallic device that is in electrical communication with the first electrolyte and the second electrolyte, the metallic device electrically coupled to a reference electrical potential, wherein the metallic device is an impeller of a pump; and
a controller including executable instructions stored in non-transitory memory that when executed enable the controller to:
supply, via the pump, the first electrolyte to the positive reactor of the electric energy storage cell and the second electrolyte to the negative reactor of the electric energy storage cell; and
electrically couple the first electrolyte to the second electrolyte via the metallic device.
