Abstract: A porous molding for an electrochemical module. The electro-chemical module has at least one electrochemical cell unit having a layer construction with at least one electrochemically active layer, and a metallic, gastight housing which forms a gastight process gas space with the electrochemical cell unit. The housing extends on at least one side beyond the region of the electrochemical cell unit, and forms a process gas conduction space open to the electrochemical cell unit, and in the region of the process gas conduction space has at least one gas passage opening for the supply and/or removal of the process gases. The porous molding is formed as a separate component of the electrochemical cell unit and is configured for arrangement within the process gas conduction space and also for support of the housing on both sides along a stack direction of the electrochemical module.

Abstract: A porous or at least sectionally porous gas conduction part is provided for an electrochemical module. The electrochemical module has at least one electrochemical cell unit having a layer construction with at least one electrochemically active layer, and a metallic, gastight housing which forms a gastight process gas space with the electrochemical cell unit. The housing extends on at least one side beyond the region of the electrochemical cell unit, and forms a process gas conduction space open to the electrochemical cell unit, and in the region of the process gas conduction space has at least one gas passage opening for the supply and/or removal of the process gases. The gas conduction part here is adapted for arrangement within the process gas conduction space and its surface is functionalized for interaction with the process gas.

Abstract: An electro-chemical module has a porous plate-shaped metallic carrier substrate with a gas-permeable central region and a peripheral region. A layered construction is disposed in the central region on a first side of the carrier substrate. At least one metallic gas-tight housing part is by way of a welded connection connected to the peripheral region of the carrier substrate. A gas-tight zone extends from the layered construction up to the housing part. The gas-tight zone has a gas-tight surface portion which extends superficially from the layered construction on the first side of the carrier substrate at least up to the welded connection. 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 of which extends only through part of the thickness of the carrier substrate.
