  • Patent number: 12126057
    Abstract: 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.
