Abstract
The invention relates to a hydrogen-air secondary cell that finds application for supplying electrical energy to systems of electric cars and portable equipment such as telephones, photographic equipment and laptops. The hydrogen-air secondary cell is characterized in that it contains an electrode made of a material capable of high hydrogen sorption capacity through the electrochemical decomposition of water, connected to the negative pole, disposed between conventional air diffusion electrodes, with at least one auxiliary electrode with lowered oxygen release overpotential being positioned between the air electrodes and the hydrogen sorption electrode, and connected electrically to an auxiliary pole of the cell and charging the cell, the electrodes being kept apart by a separator.
