The invention relates to a method for a fabrication of a pore comprising membrane and a pore comprising membrane. The pore comprising membrane (1) comprises at least a porous metallic layer (3) on a porous substrate (6), wherein the porous metallic layer (3) is connected to the porous substrate (6) and the pores (4) of the metallic layer (3) overlap at least partially with the pores (7) of the porous substrate (6). The method comprises at least the following steps: i) deposition of the metallic layer (3) onto a support material (2), wherein the deposited metallic layer (3) forms a plurality of feedthroughs, in particular a percolation network on the support material (2), ii) removal of the support material (2), iii) connecting of the metallic layer (3) with the porous substrate (6) such that pores (4) of the metallic layer (3) overlap at least partially with the pores (7) of the porous substrate (6).

A method is provided for producing a green paper for producing a gas diffusion layer (GDL) for a fuel cell. A first paper web is formed, and a second paper web is formed, which are brought together with and rigidly connected to the first paper web while still wet. The first paper web and the second paper web are mixed with metal powder and/or metal fibers and together form the green paper, optionally together with additional components and/or coatings. The final GDL is provided after a binding-removal process, a sintering process, a coating process, a (thermal) deposition process (atomic layer deposition process, ALD), and optionally additional process steps.

In the method of manufacturing the fuel cell stack and the method of manufacturing the joint separator, a joint separator is formed by joining a first metal separator and a second metal separator to each other in a state of being stacked together in a thickness direction in a manner so that bead structures of the first separator and the second separator protrude outward, and then a preliminary load is applied to the passage bead portions and the outer peripheral bead portions while suppressing deformation of a portion in a gap of a double bead portion of each of the first and second separators, the double bead portions being formed by the passage bead portion and the outer peripheral bead portion extending in parallel to each other at a narrow interval.

The invention related to metal-supported solid oxide fuel cells (SOFC), fuel cell stacks containing the same, methods of their manufacture and use thereof. The SOFC of the invention utilizes an extended electrolyte and barrier layers to prevent specific types of corrosion of the metal substrate. This new coating approach reduces the rate of degradation of the fuel cells and improves system reliability when operated over long durations.
