DESIGN AND DEVELOPMENT OF A LIQUID METAL FUEL CELL

Abstract

Substantial progress has been made in the study and operation of potassium-mercury cells and in pointing up problem areas requiring solution. Six different types of cells were run, some utilizing a ceramic matrix while others operated on a differential density principle. Certain cells were operated with flowing cathode metal, so that steadiness of operation and regenerative capability could be studied. Results confirmed this regenerative capability up to 60 mw/sq. cm, the operating level of the experiment. Liquid metal cell life was extended to as long as 550 hours to date. Current densities of 227 ma/sq. cm and power densities of 91 mw/sq. cm were achieved. Composite matrices composed of 6-micron MgO particles were produced, and electrical conductivities of discs of various electrolyte/MgO ratios were measured. Results conform to requirements of liquid metal cell systems.
