Abstract:

In accordance with the present invention, an electrochemical system is provided which comprises a plurality of cells, the cells being formed by spaced apart bipolar electrodes. Each of the electrodes is formed by an anode portion formed from a magnesium containing material and an electrocatalytic material joined to a surface of the anode. The electrodes are spaced such that the anode portion of one electrode faces the electrocatalytic material of the adjacent electrode. The electrochemical system also comprises a manifold system for introducing a seawater-catholyte solution into the spaces between the electrodes. An electrical connection is provided across the cells so as to initiate the reduction of the seawater-catholyte solution at the electrodes and to create electrical power. In a preferred embodiment, the seawater-catholyte solution is a seawater-hydrogen peroxide or seawater-sodium hypochlorite solution. A process for generating electrical power using the electrochemical system of the present invention is also described.
