NOVELTY - The energy storage and power generation system (10) comprises a fuel cell (40), into which an oxidation agent and a storable fuel electrochemically convertable and electric power is producible, and an electrolysis cell (30), which serves for producing the storable fuel for the fuel cell, where a common electrode (21) divides the fuel cell and electrolysis cell. The fuel cell and the electrolysis cell use a further electrode only for themselves. The fuel is storable in a storage unit outside the fuel cell and outside the electrolysis cell. The common electrode serves as anode of the fuel cell.    USE - Energy storage and power generation system useful for producing electricity.    ADVANTAGE - The energy storage and power generation system ensures economical production of the electricity is space-saving and can be simply and economically manufactured with less material requirements.    DETAILED DESCRIPTION - The energy storage and power generation system (10) comprises a fuel cell (40), into which an oxidation agent and a storable fuel electrochemically convertable and electric power is producible, and an electrolysis cell (30), which serves for producing the storable fuel for the fuel cell, where a common electrode (21) divides the fuel cell and the electrolysis cell. The fuel cell and the electrolysis cell use a further electrode only for themselves. The fuel is storable in a storage unit outside the fuel cell and outside the electrolysis cell. The common electrode serves as an anode of the fuel cell and as a cathode (41) of the electrolysis cell, so that the fuel in the electrolysis cell is formed at the common electrode and is convertable into the fuel cell at the common electrode. The common electrode has a porous material. An area of the common electrode has a catalyst, to which an electrolytic film adjoins. The catalyst and the electrolytic film are usable for the fuel production and for the electric power generation. The common electrode has channels, which are permeable only for the porous area for the fuel. The electrolytic film is implemented in acid or alkaline and is formed as liquid or solid electrolyte. The fuel is hydrogen, which is storable in molecular form under pressure. The oxidation agent required in the fuel cell is producible in the electrolysis cell during the operation of the electrolysis cell, is storable in a further storage unit and is supplyable to the fuel cell during the operation of the fuel cell. Several fuel cells and same number of electrolysis cells are stacked one upon the other, where the fuel cells and the electrolysis cells are electrically connected in series or parallel. Two fuel cells and two electrolysis cells are alternatively stacked one upon the other.
