The invention relates to a fuel cell consisting of a stack of elementary cells and interconnectors ( 7 ) and comprising a single vertical seal ( 2 ) which is placed around the stack thus formed. The aforementioned assembly is preferably equipped with a containment tube ( 1 ) which is placed around the vertical seal ( 2 ). Supply channels ( 11 and 12 ) in the interconnectors and lateral inlet and outlet ( 13 and 14 ) holes can be used to supply distribution channels ( 9 and 10 ) which are positioned against the electrodes of each elementary cell. The invention is suitable for SOFC-type fuel cells.
