Abstract
An electrochemical cell for the electrolysis of liquid water or water vapor includes a proton-conducting electrolyte (3) made of aluminosilicate, sandwiched between a porous metal anode (2) and a porous electronic conducting cathode (4). Preferably, the porous metal anode (2) is a sintered stainless alloy comprising at least 18% chromium. Also, a method of manufacturing such a cell includes at least: —manufacturing the proton-conducting aluminosilicate electrolyte (3) and deposition of said electrolyte (3) on the porous metal anode (2) by hydrothermal method, and —depositing the electronic conducting porous cathode (4) on the electrolyte (3) to form the electrochemical cell (1). The electrochemical cell can be used for, amongst other compounds, the reduction of oxidized compounds, such as the oxidized compounds constituted, for example, by carbon dioxide.
