Abstract: The fuel cell base module stacking structure has large compactness, very litte ohmic losses and ease as for implementing the seal of the assembly. It consists of a concentric stack of several fuel cell base cells each consisting on either side of an interconnector (24) sandwiching an anode (21), an electrolyte (22) and a cathode (23), each cell being thereby placed upon each other. The module is completed with two cases for distributing combustible gases. Application to gas fuel cells of the SOFC type.

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.
