摘要:
The invention relates to a bipolar plate for application in a fuel cell, comprising a channel forming structure. The bipolar plate further comprises, at least partly, a porous region, which borders a formed channel. According to the invention, in a fuel cell with the above bipolar plate, an improved distribution of the operating material under differing load conditions ( high and low throughflow) with reduced pressure loss is made possible by means of the combination of channels and open pores within the porous region. The above regularly leads to an improved efficiency for the fuel cell.
摘要(中):
本发明涉及一种双极板在燃料电池中,该方法包括形成一个槽形结构中使用。 此外,双极板至少部分地包括邻近于形成有沟道的多孔区域。 在具有根据本发明的双极板的资源的不同负载条件(高和低流速)下的改进的分布的燃料电池能够通过多孔区域内的通道和开孔的组合的减少压力损失。 这经常导致燃料电池的效率更高。
