And the bipolar plate is light and efficient. The invention relates to a bipolar plate for a fuel cell stack, comprising: a first main boundary surface; a second main boundary surface; wherein the first main boundary surface and the second main boundary surface are arranged parallel to and at a distance from each other and define an interior space; wherein the plurality of lateral defining surfaces extend between the outer edges of the first and second main boundary surfaces to enclose the interior space; wherein at least one of the lateral defining surfaces comprises a plurality of lateral openings; wherein at least one of the main boundary surfaces comprises a plurality of axial openings; wherein the plurality of internal distribution channels are arranged within the interior space at a distance from the first main boundary surface and the second main boundary surface; and wherein the lateral opening of each of the at least one lateral delimiting face is fluidly connected with the axial opening of one of the at least one main delimiting face through at least a portion of the internal distribution channel.

    轻质且高效的双极板。本发明涉及一种用于燃料电池堆的双极板,其包括:第一主边界面;第二主边界面;其中该第一主边界面和第二主边界面布置成彼此平行且相距一定距离,并且限定内部空间;其中多个侧向界定面在第一主边界面和第二主边界面的外边缘之间延伸,以封围内部空间;其中侧向界定面中的至少一个侧向界定面包括多个侧向开口;其中主边界面中的至少一个主边界面包括多个轴向开口;其中多个内部分配通道在内部空间内部布置成与第一主边界面和第二主边界面相距一定距离;并且其中所述至少一个侧向界定面中的每个的侧向开口通过内部分配通道的至少一部分、与所述至少一个主边界面中一个的轴向开口流体连接。
