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: The bipolar plate is of a relatively simple design and a low production cost. In addition, it only requires two supply ducts. It consists essentially of a separator (20) sandwiched between two distributors (14) each consisting of a deformed sheet so that a distribution channel (16A, 16B) is formed on each of the two sides. A central hole (15) is used to connect both channels so as to only form a single distribution channel from one end of the distributor to the other. The fuel and oxidant gases may be evacuated to the outside or collected in peripheral evacuation holes (28) similar to the supply holes (17).

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.

Abstract: The present invention relates to a method of coating a surface with nanoparticles, to a nanostructured coating that can be obtained by this method, and also to a device for implementing the method of the invention. The method is characterized in that it comprises an injection of a colloidal sol of said nanoparticles into a plasma jet that sprays them onto said surface. The device (1) comprises: a plasma torch (3); at least one container (5) containing the colloidal sol (7) of nanoparticles; a device (9) for fixing and for moving the substrate(S); and a device (11) for injecting the colloidal sol into the plasma jet (13) of the plasma torch. The present invention has applications in optical, electronic and energy devices (cells, thermal barriers) comprising a nanostructured coating that can be obtained by the method of the invention.
