Abstract
An anode-side half cell for an electrochemical cell of an electrolytic apparatus for carbon dioxide electrolysis and/or carbon monoxide electrolysis, having a separator in the form of a diaphragm, which has an anode-side separator surface and a cathode-side separator surface opposite the anode-side separator surface; a catalyst layer, which has a first catalyst surface and a second catalyst surface opposite the first catalyst surface, the first catalyst surface facing the anode-side separator surface; and a fluid-permeable anode plate, which has a first anode surface, the first anode surface facing the second catalyst surface.
Claims14
An anode-side half-cell for an electrochemical cell of an electrolysis device for carbon dioxide electrolysis and/or for carbon monoxide electrolysis, comprising:
- a separator which is in the form of a membrane and has an anode-side separator surface and a cathode-side separator surface on the opposite side from the anode-side separator surface,
- a catalyst layer having a first catalyst surface and a second catalyst surface on the opposite side from the first catalyst surface, wherein the first catalyst surface faces the anode-side separator surface,
- a fluid-permeable anode plate having a first anode surface, wherein the first anode surface faces the second catalyst surface,
- wherein the second catalyst surface comprises cylindrically shaped projections that protrude from this surface and project into the anode plate through the first anode surface for bonding to the anode plate,
- wherein the first anode surface comprises cylindrically shaped receiving openings for receiving the cylindrically shaped projections;
- and
- wherein the cylindrically shaped projections and the cylindrically shaped receiving openings cooperate to define a releasable plug-connection between the catalyst layer and the anode plate.
A method of producing an anode-side half-cell for an electrochemical cell of an electrolysis device for carbon dioxide electrolysis and/or for carbon monoxide electrolysis, comprising:
- arranging an anode-side separator surface of a separator which is in the form of a membrane and has a cathode-side separator surface on the opposite side from the anode-side separator surface at a first catalyst surface of a catalyst layer, which catalyst layer has a second catalyst surface on the opposite side from the first catalyst surface,
- arranging a first anode surface of a fluid-permeable anode plate at the second catalyst surface,
- wherein the second catalyst surface has cylindrically shaped projections that protrude from this surface and project into the anode plate through the first anode surface for bonding to the anode plate,
- wherein the first anode surface comprises cylindrically shaped receiving openings for receiving the cylindrically shaped projections;
- and
- wherein the cylindrically shaped projections and the cylindrically shaped receiving openings cooperate to define a releasable plug-connection between the catalyst layer and the anode plate.
