Interconnecting device for solid oxide fuel cells and a fuel cell stack comprising the same

An interconnecting device for compact solid oxide fuel cells, the interconnecting device comprising a body having a first interface surface, and a second interface surface on distinct sides of the body,

• wherein the first interface surface comprises at least one anode exhaust input and at least one cathode exhaust input in a distance to the at least one anode exhaust input,
• wherein the second interface surface comprises at least one fuel supply port and at least one oxidant supply port in a distance to the at least one fuel supply port,
• wherein the at least one anode exhaust input is in fluid communication with at least one of the at least one fuel supply port or at least one anode exhaust outlet arranged at a distance to the first interface surface and the second interface surface,
• wherein the at least one cathode exhaust input is in fluid communication with the at least one of the at least one oxidant supply port or at least one cathode exhaust outlet arranged at a distance to the first interface surface and the second interface surface,
• wherein at least one first electrical port is arranged at or in the at least one cathode exhaust input and is connectable from the first interface surface,
• wherein at least one second electrical port is arranged at or in the at least one fuel supply port and is connectable from the second interface surface, and
• wherein the at least one first electrical port is electrically connected to the at least one second electrical port.
