Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur elektrochemischen Umsetzung eines Gases umfassend CO2 sowie eine Vorrichtung zur elektrochemischen Umsetzung eines Gases umfassend CO2, wobei an einer Kathode einer Elektrolysezelle, welche ein Metall umfasst, das ausgewählt ist aus der Gruppe umfassend Ag, Au, Zn, Pd, Cu, und/oder Legierungen und/oder Mischungen davon, ein Gas umfassend CO2 umgesetzt wird, bevorzugt zu einem Produktgas umfassend CO, und wobei an einer Anode der Elektrolysezelle ein Gas umfassend H2 zu einem Produkt umfassend Protonen umgesetzt wird.
(EN)
The present invention relates to a method for the electrochemical conversion of a gas comprising CO2 and an apparatus for the electrochemical conversion of a gas comprising CO2, wherein a gas comprising CO2 is converted at a cathode of an electrolysis cell, which comprises a metal selected from the group comprising Ag, Au, Zn, Pd, Cu and/or alloys and or mixtures thereof, preferably to form a product gas comprising CO, and wherein a gas comprising H2 is converted at an anode of the electrolysis cell to form a product comprising protons.
(FR)
L'invention concerne un procédé de conversion électrochimique d'un gaz comprenant du CO2, ainsi qu'un dispositif de conversion électrochimique d'un gaz comprenant du CO2. Un gaz comprenant du CO2 est converti sur une cathode d'une cellule électrolytique, qui comprend un métal choisi parmi le groupe comprenant Ag, Au, Zn, Pd, Cu et/ou des alliages et/ou des mélanges de ces derniers, de manière préférée en un produit gazeux comprenant du CO. Un gaz comprenant du H2 est converti sur une anode de la cellule électrolytique en un produit comprenant des protons.
