A pump is disclosed which utilizes battery gas for circulating a body of liquid electrolyte in an electrochemical cell. The pump comprises an electrolyte conduit immersed in the electrolyte body and having an electrolyte inlet adjacent the bottom of the electrolyte body, an electrolyte outlet closely below the surface of the body, and a gas inlet below the outlet. The pump also comprises a hood for collecting battery gas rising in the electrolyte body and a passage for conveying collected gas from the hood to the conduit gas inlet. Gas bubbles released into the conduit at the gas inlet rise and carry electrolyte to the outlet, thereby circulating the electrolyte.

An electrolyte circulation pump adapted for use in an electrochemical cell comprising a body of liquid electrolyte confined in a vented container and in which gas bubbles form in the electrolyte during cell operation, said pump comprising conduit means having an inlet and outlet for said electrolyte

An electrolyte circulation pump adapted for use in an electrochemical cell comprising a body of liquid electrolyte confined in a vented container and in which gas bubbles form in the electrolyte during cell operation, said pump comprising conduit means having an inlet and outlet for said electrolyte and adapted to be immersed in said electrolyte body with the inlet at a level below the outlet, said conduit further having a gas inlet below the level of said outlet such that gas bubbles introduced into the conduit through the gas inlet carry electrolyte from the electrolyte inlet to the electrolyte outlet, thereby inducing circulation of said electrolyte body, and means for collecting gas rising in said body and conducting it to said gas inlet to effectuate said circulation, said means comprising an upwardly convergent baffle member adapted to be immersed in said electrolyte body to intercept the bubbles and to collect the gas therefrom and a passage for gas to flow from said baffle to said conduit gas inlet.
