FUEL CELL STACK, FUEL CELL SYSTEM, AND PRODUCTION METHOD FOR PRODUCING A FUEL CELL STACK

The presented invention relates to a fuel cell stack (100) for providing electrical energy. The fuel cell stack (100) comprises a number of bipolar plates (BPP) (101) and a number of membrane electrode assemblies (MEA) (103). Respective MEA (103) of the number of MEA (103) and respective BPP (101) of the number of BPP (101) are stacked on each other in alteration. The MEA (103) and the BPP (101) each have an opening (105, 300, 400, 500), and the openings (105, 300, 400, 500) of all the MEA (103) and the BPP (101) jointly form an alignment receptacle (109) for receiving an alignment tool (107).The membrane electrode assemblies (MEA) (103) protrude, at least in parts, further into the alignment receptacle (109) than each bipolar plate (BPP) (101), so that adjacent BPP (101) surrounding one of the MEA (103) are electrically insulated from each other by said MEA (103).
