Bipolar plate for electrochemical application, has passage opening guiding fuel and/or oxidizer and insertion unit arranged between top layers in area of opening, where point-forces are induced in two-dimensional manner by unit

摘要

The plate has a supporting layer arranged between top layers and connected with the layers. The supporting layer has a column at an attachment area for the top layers and is formed between adjacent attachment areas of a free space. A passage opening (128) guides fuel and/or oxidizer, and an insertion unit (140) is arranged between the layers in an area of the opening, where point-forces are induced in two-dimensional manner by the unit. Independent claims are also included for the following: (1) a method for manufacturing a bipolar plate (2) a fuel cell block arrangement comprising a bipolar plate.
