Fuel cell

The invention relates to a fuel cell (10) having a stack comprising a bipolar plate (20) which has a flow field (22) formed by a profiled section of the bipolar plate (20), an elongated sealing element (21), which at least partially surrounds the flow field (22), and a membrane electrode assembly (30). According to the invention, a filling agent (24) is arranged inside a cavity (25) formed between the membrane electrode assembly (30) and the bipolar plate (20), in a region between the sealing element (21) and the flow field (22), said filling agent extending in the extension direction of the cavity (25). 本发明涉及种带有堆栈的燃料电池(10)，包括：双极板(20)，该双极板(20)具有流场(22)，该流场(22)通过双极板(20)的成型部构造，以及纵向延伸的密封元件(21)，该密封元件(21)至少部分包围流场(22)；和膜片电极单元(30)。设置成，在空腔(25)内布置有在空腔(25)的延伸方向上延伸的填充体(24)，该空腔(25)构造在膜片电极单元(30)与双极板(20)之间在密封元件(21)与流场(22)之间的区域中。
