ELECTROCHEMICAL MODULE

摘要

The invention relates to an electrochemical module (4) which has a porous plate-shaped metal carrier substrate (8) with a gas-permeable central region (10) and an edge region (12); a layer structure (26) arranged on a first face (13) of the carrier substrate in the central region; at least one gas-tight metal housing part (14) connected to the edge region of the carrier substrate via a welded connection (18); and a gas-tight zone (32) that extends from the layer structure to the housing part. The gas-tight zone has a gas-tight surface section (30), which extends from the layer structure at least to the welded connection over the surface of the first face of the carrier substrate, and the gas-tight zone also has the welded connection, by means of which the gas-tight surface section is connected to the housing part in a gas-tight manner and the welding zone (36) of which extends through only one part of the thickness of the carrier substrate.
