Abstract
The present disclosure relates to a bipolar plate for an electrochemical system and an electrochemical system comprising at least one such bipolar plate. The bipolar plate comprises a first separator plate and a second separator plate, which are arranged on top of each other. At least one of the separator plates has, on the side that faces the other separator plate, only partially coated surface areas, which are provided with a coating that increases the electrical conductivity.
Claims20
A bipolar plate for an electrochemical system, having a first separator plate (2a) and a second separator plate that are arranged one on top of the other, wherein
- the first separator plate has, on a side that faces away from the second separator plate, embossed webs and channels for guiding a first fluid;
- the second separator plate has, on a side that faces away from the first separator plate, embossed webs and channels for guiding a second fluid;
- the first and second separator plates each have webs and channels on mutually facing sides for guiding a cooling medium along an inner side of the bipolar plate;
- wherein at least one of the first separator plate and the second separator plate has, on the side that faces the other separator plate, coated surface regions only in sections, wherein the coated surface regions are provided with a coating that increases an electrical conductivity.
