An interconnector plate for a fuel cell and a fuel cell system for an aircraft. For better extraction of the energy generated by the fuel cell, an interconnector plate can be attached by form fit to fixing studs of the fuel cell by retaining eyes. The interconnector plate may additionally be secured using glass solder. In preparation for a higher power density, a fuel cell can be produced in ceramic by 3D-printing and has an improved power density because of its helical shape.

A fuel cell has a tunnel protruding from a passage bead seal toward a passage to thereby allow an internal space of the passage bead seal to communicate with the passage, and an extending portion located on a side of the tunnel so as to extend from the passage bead seal toward the passage, the extending portion being lower in height than the tunnel.

A first separator member forming a power generation cell, which is a fuel cell, includes a first separator body. A first support bead, which is formed to be lower in height than a first seal bead and restricts the inclination of the first seal bead, is provided outside a first seal in the first separator body. The width of the first support bead varies depending on the position of the first support bead in the direction in which the first support bead extends.
