ARRANGEMENT FOR THE ALIGNMENT OF A MEMBRANE-ELECTRODE-ASSEMBLIES WITHIN A STACK DURING ASSEMBLY

摘要

An electrochemical system has two separator plates as well as a membrane-electrode assembly arranged at least in regions between the separator plates. The separator plates and the membrane-electrode assembly each have at least two passage openings for a flush arrangement of the separator plates and the membrane-electrode assembly at positioning devices during the assembly of the electrochemical system. At least one resilient bridge is arranged at the periphery of at least one passage opening for a mechanical butting to the at least one positioning device in such a manner that during the stacking of the separator plates and the membrane-electrode assemblies, the membrane-electrode assemblies center themselves in a direction orthogonal to the stack direction between the separator plates.
