Patent ID: 7887959

Claim:
Fuel cell module formed of a concentric stack ( 20 ) of elementary cells of tubular geometry having a common co-axial axis with each elementary cell consisting of an anode ( 21 ), an electrolyte ( 22 ) and a cathode ( 23 ), and being in contact with two interconnects ( 10 , 10 E, 10 I), the module consisting of a concentric stack ( 20 ) of several concentric cells and several interconnects disposed in a concentric arrangement with the module completed on each side by a distribution and exhaust namely a base ( 50 ) and a flange ( 40 ) characterized in that the concentric interconnects ( 10 , 10 E, 10 I) have a central partition ( 13 ) on which at least one flexible metal collar ( 11 ) is flanged to form a notch that lies at an angle away from the central partition ( 13 ).
