Abstract
The invention relates to a fuel cell module (21, 22) for PEM fuel cell stacks comprising a bipolar plate (2) and a membrane-electrode assembly (MEA) (3), wherein the bipolar plate (2) includes a circumferential frame (5) made of an electrically nonconductive material and further includes an electrically conductive inner bipolar plate region (6) which is enclosed by the frame (5) and comprises channels for gases and, if required, for coolants, and wherein the MEA (3), which comprises a polymer-electrolyte membrane is fixed on the anode side to the frame (5) of the bipolar plate (2) by means of a weld or by a circumferential elastomer seal partially overlapping the MEA (3).
