Abstract
A separator plate for at least one fuel cell of a fuel cell system is provided. The separator plate includes at least one seal, wherein the seal is designed to seal at least one media-conducting inner region from a non-media-conducting outer region. The separator plate additionally includes at least one spacer element, which is preferably arranged in the outer region. The separator plate can be contacted by an evaluating device in a contacting region, this region being located such that it lies, in part, between the seal and spacer element. According, a deformation of the separator plate in the contacting region within a fuel cell stack is thus prevented.
