Abstract
The present invention relates to a cell for the production of electric energy by reaction between hydrogen peroxide or oxygen, and aluminium or lithium or a mixture thereof, and hydroxyl ions in water, where the cathodes are cylindrical and based on radially oriented carbon fibres attached to a stem of metal. The novel feature of the invention is that by utilizing such cathodes in a cell with circulating electrolyte, it is possible to keep the concentration of oxidant in the electrolyte low and thus obtain high utilization of the reactants.
