FUEL CELL WITH CURRENT COLLECTORS INTEGRATED WITH THE SOLID ELECTROLYTE AND PROCESS FOR MANUFACTURING SUCH A FUEL CELL

摘要

A fuel cell comprises at least two current collectors (4, 5), an electrically insulating separator element (2) and a solid electrolyte (6). Each current collector (4, 5) includes at least one transverse passage (4c, 5c) that passes through it from a first surface (4a, 5a) to a second surface (4b, 5b) and the separator element (2), having first and second opposed faces, is placed between the current collectors (4, 5). A plurality of transverse channels (2c) passes through the separator element (2) from the first face to the second face, and the ionically conducting solid electrolyte (6) occupies the volume bounded by the channels (2c) of the separator element (2) and by the passages (4c, 5c) of the current connectors (4, 5). The separator element (2) is formed by a thermoplastic polymer material and hard particles (8) are placed in transverse channels (2c).
