Abstract

Disclosed is a solid oxide fuel cell (SOFC) positive electrolyte negative (PEN) comprising electrodes on the rear side thereof used for establishing contact between a flat interconnecting plate and a raised structure which is configured in such a way that it forms gas circulation channels with said plate. The PEN and interconnecting plates can have holes so as to create internal gas inlet and outlet tubes. The electrolyte/electrode interface can also be configured as a raised structure increasing the ratio of the extended area to the projected area.
