Attitude and gravity insensitive galvanic cell
Abstract
Abstract AN ALKALI METAL (ALKALI METAL HALIDE) HALOGEN GALVANIC CELL INCLUDING AN EXCESS ELECTROLYTE RESERVOIR, AN ELECTROCHEMICALLY ACTIVE REGION FILLED WITH ELECTROLYTE AND CONTAINING THE CELL''S ELECTRODES, AND A POROUS, CARBON OR GRAPHITE, NONELECTROLYTE-WETTABLE, ELECTROLYTE FLOW RESRICTOR LOCATED BETWEEN THE RESERVOIR AND THE REGION. THE RESTRICTOR KEEPS THE REGION FILLED AND THE ELECTRODES COVERED WITH ELECTROLYTE REGARDLESS OF THE CELL''S ORIENTATION AND ACTS AS AN ELECTROLYTE RELIEF MEANS TO PREVENT EXCESSIVE ELECTROLYTE PRESSURE BUILDUP IN THE REGION. THE RESTRICTOR''S PORES ARE LARGER THAN THE PORES OF THE CARBON OR GRAPHITE HALOGEN ELECTRODE SUCH THAT THE FLOODING PRESSURE OF THE RESTRICTOR IS LESS THAN THE FLOODING PRESSURE OF THE ELECTRODE.
