Beschreibung
Zusammenfassung:	The fuel cell stack (3) has several stacked fuel cells (1). Each stacked fuel cells is provided with the bipolar plates (1.1,1.2), and a membrane-electrode assembly (1.3). The frame elements (1.1.1,1.2.1) are mounted on the bipolar plate and on the membrane-electrode assembly at fluid-tightly. The frame element (1.1.1) of bipolar plate (1.1) is connected with the frame element (1.2.1) of the adjacent bipolar plate (1.2). An independent claim is included for method for manufacturing fuel cell stack. Die Erfindung betrifft einen Brennstoffzellenstapel (3), umfassend eine Mehrzahl gestapelter Brennstoffzellen (1), welche jeweils zumindest aus einer Bipolarplatte (1.1, 1.2), einer Membran-Elektroden-Einheit (1.3) und einem Rahmenelement (1.1.1, 1.2.1) gebildet sind, wobei das Rahmenelement (1.1.1, 1.2.1) zumindest an der Bipolarplatte (1.1, 1.2) und/oder an der Membran-Elektroden-Einheit (1.3) fluiddicht befestigt ist. Erfindungsgemäß ist das Rahmenelement (1.1.1) einer ersten Bipolarplatte (1.1) mit dem Rahmenelement (1.2.1) der benachbarten zweiten Bipolarplatte (1.2) stoffschlüssig verbunden. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Brennstoffzellenstapels (3).
