Beschreibung
Zusammenfassung:	The invention relates to an isolation device (9) configured to be mounted in a fluid flow channel of a fuel cell comprising a stack including a plurality of cells aligned along a stack axis X and a plurality of fluid flow channels in the stack, the isolation device (9) comprising a peripheral belt (90) configured to block the fluid communication between the flow channel and at least one flow opening of a cell to be isolated in the stack, the belt (90) being deformable between a first configuration, referred to as an idle configuration, and a second configuration, referred to as a constricted configuration, the cross-section of which is smaller than in the first configuration.
