Abstract : This invention is related to control of spacing between consumable electrodes in an electrochemical energy source. The electrochemical reaction between an active metal such as magnesium and a passive metal such as iron in an electrolyte such as seawater has been used for the production of electrical energy in seawater batteries and also for the production of heat in a magnesium seawater diver heater. The device disclosed herein offers a simple, reliable, and economical approach to maintaining a constant reaction rate, other parameters being constant, in electrochemical batteries, heaters, or hydrogen generators which use a consumable anode and inert cathode immersed in a liquid electrolyte. The spacing control rate can be preset to adust for other cell parameters which might influence cell output over a period of time.
