Abstract
The invention relates to a SOFC stack with bipolar plates (5) for connecting the electrodes (3, 4) of two neighboring fuel cells having a ceramic electrolyte, where the bipolar plates (5) have one base plate (6) each, and connected to it, one or more contact elements (7) on one on both sides of the base plate (6). The bipolar plates are characterized in that the base plate (6) is rigid and gas-tight and the contact elements (7) are elastically or plastically deformable, and are arranged or implemented in such a way that they are permeable to gas perpendicularly to the plane of the base plate (6). The bipolar plates (5) mechanically stabilize the SOFC stack and ensure the reliable contacting of the electrodes (3, 4), wherein manufacturing tolerances of the electrodes (3, 4) and relative movements between the components of the stack are compensated by thermal expansion or creep processes.
