    摘要： The invention provides a bipolar plate for a fuel cell (2) which can be produced in a particularly cost-effective manner, in the case of which high efficiency is ensured over a long use period. For this purpose, the bipolar plate has a core layer consisting of a steel material, the surfaces of said core layer which are associated with the respective electrolyte carrier of the fuel cell each being provided with an anti-corrosion layer protecting the core layer from corrosion. According to the invention, in this case the anti-corrosion layers are each made from a metal material and extend on both sides in each case completely over the core layer (10). At the same time, the anti-corrosion layers (11, 12) for their part are each completely covered by an electrically conductive functional layer (13, 14), which is substantially completely impermeable to metal ions emerging from the core layer (10) and/or the anti-corrosion layers (11, 12). The invention likewise relates to a fuel cell comprising at least one bipolar plate according to the invention.

    摘要翻译： 一种双极板，其可以特别经济地用于燃料电池，在长期使用寿命期间可保证高效率。 双极板具有由钢材组成的芯层，所述芯层的与燃料电池的各个电解质载体相关联的表面具有防腐蚀层，保护芯层免受腐蚀。 防腐层由金属材料构成，并在芯层的整个表面两侧延伸。 同时，腐蚀保护层又在整个表面上用导电功能涂层涂覆，导电功能涂层对于从芯层和/或腐蚀保护层出现的金属离子基本上完全不可渗透。 本发明同样涉及包括根据本发明的双极板的至少一个燃料电池。
