ABSTRACT:
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.
