Abstract (en)

[origin: WO2022090145A2] The invention relates to a fuel cell stack (2) having a series of cells consisting of a plurality of unit cells (4), which are formed with cell-internal media guides and are received between two end plates (3), which are braced to one another, in a fuel cell stack housing (5). The series of cells present in the fuel cell stack housing (5) is completely embedded into an electrically insulating casting material (6). The invention also relates to a method for producing a fuel cell stack (2).
