Energy storage and power generation system

摘要

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).

1. An energy storage and power generation system (10) comprising:
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; 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; and a store (13) for storing the fuel, the store located outside the fuel cell (40) and outside the electrolysis cell, wherein the common electrode (21) has both an open channel (22) and a separate porous region (23) adjacent the open channel (23), wherein the open channel (22) extends along a first direction to direct hydrogen from the store (13) along the first direction, wherein the porous region (23) is positioned to receive the hydrogen from the open channel (22) along a second direction that is perpendicular to the first direction, and to direct the hydrogen along a third direction that is perpendicular to both the first direction and the second direction.
