Abstract: An interconnect element for electrically connecting an anode and a cathode in adjacent fuel cells in a fuel cell stack, wherein said interconnect element has at least one featured surface including dimples, bosses, and/or pins arranged in a two-dimensional pattern. Preferably, both surfaces are featured, as by mechanical dimpling, embossing, or chemical etching, so that protrusions of the interconnect surface extend into either or both of the adjacent gas flow spaces to make electrical contact with the surfaces of the anode and cathode. This permits conduction of heat from the anode. The protrusions create turbulence in gas flowing through the flow spaces, which increases hydrogen consumption at the anode and hence electric output of the cell.

Abstract translation: 一种用于将燃料电池堆中的相邻燃料电池中的阳极和阴极电连接的互连元件，其中所述互连元件具有包括以二维图案布置的凹坑，凸起和/或销的至少一个特征表面。 优选地，两个表面的特征在于通过机械凹坑，压花或化学蚀刻，使得互连表面的突起延伸到相邻的气体流动空间中的任一个或两个，以与阳极和阴极的表面电接触。 这允许来自阳极的热传导。 突起在流过空间的气体中产生湍流，这增加了阳极处的氢消耗量，从而增加了电池的电力输出。
