Electrochemical cell and process

摘要

An electrochemical cell 10 has a first volume 1 exposed to an anode 28 and a cathode 24, the cell having a steam inlet 5 to allow steam into the first volume 1, characterised in that an electrically insulating porous material (4) is positioned to impede steam from the steam inlet 5 from reaching the anode 28. The insulating porous material (4) may be an aerogel and the electrodes 24, 28 may be porous gas electrodes. A source material may be steam; a first ionic component may be nitride ions; a second source material may be nitrogen and a gaseous product may be ammonia.
