Abstract

An energy storage and power generation system (10) with at least one fuel cell (40), in which an oxidant and a fuel which can be stored can be converted electrochemically and in the process an electrical current can be generated, and with at least one electrolysis cell (30), which is used for generating the fuel which can be stored for the fuel cell (40), wherein the fuel cell (40) and the electrolysis cell (30) share a common electrode (21), and the fuel cell (40) and the electrolysis cell (30) each use a respective further electrode (31, 41) only for themselves. For this purpose, the invention provides that the fuel can be stored outside the fuel cell (40) and outside the electrolysis cell (30) in a store (13).
