摘要： Disclosed is an electrolytic direct energy converter (EDEC) having a cell that produces electrical energy based on the dynamics of electrically mobile ions within a gel, fluid or solid state electrolyte that is in electrical contact with a pair of electrodes of the cell. The pair of electrodes are physically separated from one another within an electrolyte such that an electric field is generated therebetween. The motion of the ions in the electrolyte causes more of the positive ions to move to one of the pair of electrodes and more of the negative ions to move to the other one of the pair of electrodes whereby to produce a potential voltage. An external electrical load impedance is electrically connected between the pair of electrodes such that the potential voltage is produced by the cell across the load impedance and a current flows through the load impedance.
