Abstract
A fuel cell module according to the invention, of concentric type, can consist of parts fabricated independently of each other whilst ensuring efficient electric connection between these parts and the limiting of stresses inside the stack. It chiefly consists of a central stack (20) of several elementary cells of a fuel cell, separated from each other by interconnects (10). These are formed of a central metal partition carrying flexible, notched collars. The assembly is completed by a base (50) and flange (40) ensuring distribution of the combustible gases. Application to fuel cells of SOFC type.
Claims10
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, 10E, 10I), 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, 10E, 10I) 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).
