## Abstract

A holder for at least one electrode, in particular a discharge electrode which is suitable for producing a corona discharge, in an exhaust-gas line, includes a body through which an exhaust gas can flow and at least one electric contact for the at least one electrode. Preferably, the at least one electric contact is integrated into the body. An apparatus for fixing at least one electric electrode in an exhaust-gas line is also proposed. The apparatus has at least one such holder and the apparatus has a particle separator disposed downstream in exhaust gas flow direction.

## Claims

### Claim 1

A holder for at least one electrode in an exhaust-gas line, the holder comprising:
a body through which an exhaust gas can flow; and
at least one electric contact for the at least one electrode in the exhaust-gas line.

### Claim 2 (depends on 1)

The holder according to claim 1, wherein:
said at least one electrode is a discharge electrode suitable for producing a corona discharge;
said body through which the flow can occur has channels and holds the at least one electrode; and
said at least one electric contact is integrated into said body.

### Claim 3 (depends on 1)

The holder according to claim 1, wherein:
said body through which the flow can occur has at least one housing and at least one metallic honeycomb structure; and
said at least one electric contact passes through said at least one housing.

### Claim 4 (depends on 1)

The holder according to claim 1, wherein said body through which the flow can occur has at least one distributor, and said at least one distributor makes electric contact with a plurality of the electrodes in said body.

### Claim 5 (depends on 1)

The holder according to claim 1, wherein said body through which the flow can occur has at least one first channel with a channel cross section and at least one second channel with an electrode cross section.

### Claim 6 (depends on 1)

The holder according to claim 1, wherein said body through which the flow can occur is electrically segmented and has segments being at least partially isolated from one another.

### Claim 7 (depends on 1)

An apparatus for fixing at least one electric electrode in an exhaust-gas line, the apparatus comprising:
at least one holder according to claim 1; and
a particle separator disposed downstream of said at least one holder in an exhaust gas flow direction.

### Claim 8 (depends on 7)

The apparatus according to claim 7, wherein said at least one holder is a plurality of holders.

### Claim 9 (depends on 7)

The apparatus according to claim 7, wherein said at least one holder only partially spans a line cross section of the exhaust-gas line.

### Claim 10 (depends on 7)

The apparatus according to claim 7, in which the at least one holder is embodied so as to be vibrationally sensitive to exhaust-gas pulsations.
