Abstract
The invention relates to an interconnector arrangement for a fuel cell stack, which can be brought into electrical contact with at least one membrane electrode assembly and which is arranged to separate a cathode flow field of the fuel cell stack from an anode flow field of the fuel cell stack. The invention is characterized in that the interconnector arrangement comprises a hollow space separated from the anode flow field and from the cathode flow field such that a flow of gas through the hollow space may not be more than five percent of flow-off gas through the cathode flow field or the anode flow field. The invention also relates to a fuel cell stack and to a method for manufacturing an interconnector arrangement.
