Abstract
The invention relates to a separator plate, a membrane electrode assembly and a fuel cell stack, which are designed for higher voltages. It is provided that in the active region at least one of the cell components contains at least one insulating element which permanently enables different electrical potentials in a cell plane (orthogonal to the stacking direction).
