摘要： Described herein are solid oxide fuel cells (SOFCs), comprising anode-conductor seals and/or cathode-conductor seals used for sealing porous metal structures and controlling the distribution of fuel and oxidants within these porous structures. For example, a SOFC comprises an anode conductor, cathode conductor, and electrolyte, disposed between the anode and cathode conductors. The anode conductor comprises multiple porous portions (permeable to the fuel) and a non-porous portion. The SOFC also comprises an anode-conductor seal, forming a stack with the non-porous portion. This sealing stack extends between the electrolyte and current collector and separates two porous portions thereby preventing the fuel and oxidant migration between these portions. In some examples, the sealing stack forms an enclosed boundary around one porous portion of the anode conductor. In the same or other examples, another sealing stack is formed in the cathode conductor, e.g., surrounding a fuel port extending through the cathode conductor.

摘要： A proton conduction fuel cell has an anode support made of metal having a fuel flow channel, an anode comprising an anode active material in contact with the anode support, a cathode support made of metal having a cathode gas flow channel, a cathode comprising a cathode active material in contact with the cathode support, and an electrolyte layer. The electrolyte layer comprises a first layer of electrolyte formed in a lock pattern on the anode and a second layer of the electrolyte formed in a key pattern on the cathode. The second layer fits in the lock pattern of the first layer to form the electrolyte layer.

摘要： A fuel cell includes a cell structure, an oxidizing agent flow path, a fuel flow path, and an anode-side current collector. The cell structure includes a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode. The oxidizing agent flow path is formed adjacent to the cathode and away from the solid electrolyte layer. The oxidizing agent flow path is a flow path for supplying a gas that contains an oxidizing agent to the cathode. The fuel flow path is formed adjacent to the anode and away from the solid electrolyte layer. The fuel flow path is a flow path for supplying a fuel gas that contains water vapor and a hydrocarbon to the anode. The anode-side current collector is disposed adjacent to the anode and away from the solid electrolyte layer. The anode-side current collector is in contact with the anode.

摘要： A method is provided for producing a green paper for producing a gas diffusion layer (GDL) for a fuel cell. A use is described of an accordingly produced gas diffusion layer (GDL) in a fuel cell. A first paper web is loaded with metal powder and/or metal fibers, and a microporous layer (MPL) is in the form of at least one coating is applied onto the paper web. The paper web is then subjected to a binder removal process, a sintering process, a coating process, atomic layer deposition (ALD) using thermal ALD methods, and optionally additional process steps in order to obtain the final GDL. After the sintering process, all of the organic components of the green paper are pyrolyzed and thus no longer contained in the GDL, and the GDL consists virtually exclusively of a metal framework.

摘要： At least one embodiment relates to a method for transforming at least part of a valve metal layer into a template that includes a plurality of spaced channels aligned longitudinally along a first direction. The method includes a first anodization step that includes anodizing the valve metal layer in a thickness direction to form a porous layer that includes a plurality of channels. Each channel has channel walls and a channel bottom. The channel bottom is coated with a first insulating metal oxide barrier layer as a result of the first anodization step. The method also includes a protective treatment. Further, the method includes a second anodization step after the protective treatment. The second anodization step substantially removes the first insulating metal oxide barrier layer, induces anodization, and creates a second insulating metal oxide barrier layer. In addition, the method includes an etching step.

摘要： A method for welding between two metallic plates, including:



(a) fitting a solid plate without openings, configured to be transparent at at least one emission wavelength of a laser beam (F) emitted by a laser (L), between the laser (L) and at least one contact zone between the metallic plates to be welded;
(a1) inerting of the contact zone via a netural gas, where the neutral gas circulates in channels delimited by the contact zone between the metallic plates and by the solid plate;
(a2) exerting pressure on the two metallic plates to apply them against one another in the contact zone to be welded, where the application pressure is exerted by the solid plate directly in contact with one of the two metallic plates to be welded; and
(b) emission of a laser beam, through the solid plate, to perform welding of the metallic plates in the contact zone.
