ELECTRO-CHEMICAL MODULE

The present invention relates to an electro-chemical module (4) which has a porous plate-shaped metallic carrier substrate (8) having a gas-permeable central region (10) and a peripheral region (12);a layered construction (26) which is disposed in the central region on a first side (13) of the carrier substrate; at least one metallic gas-tight housing part (14) which by way of a welded connection(18) is connected to the peripheral region of the carrier substrate; and a gas-tight zone (32) extending from the layered construction up to the housing part. The gas-tight zone has a gas-tight surface portion (30) which extends superficially from the layered construction on the first side of the carrier substrate at least up to the welded connection; and the welded connection by which the gas-tight surface portion is connected in a gas-tight manner to the housing part and the welding zone (36) of which extends only through part of the thickness of the carrier substrate. 本发明涉及电化学模块(4)，其具有：多孔板形金属载体基板(8)，其具有可透气的中央区域(10)
