A connector system for use in connecting a fuel cell plate to an electrical device includes first arms elastically deformable toward each other to allow an insertion of the first arms into a first slot of a fuel cell plate and elastically returnable to provide a force against a surface of the fuel cell plate to hold the arms against the fuel cell plate, and second arms elastically deformable toward each other to allow an insertion of the second arms into a second slot of an electrical device and elastically returnable to provide a force against a surface of the electrical device to hold the arms against the electrical device. The first arms are connected to the second arms at intersecting points allowing movement of the first arms relative to the second arms.

A solid oxide fuel cell stack has a surface from which via conductors for drawing a current are exposed. Collector plates are disposed on the surfaces of the fuel cell stack so that one main surface of the collector plates faces the via conductors. Fixing plates are fixed to the collector plates. Spacers are disposed between the fuel cell stack and the fixing plates. An adhesive fixes the fixing plates to the fuel cell stack through the spacers.

The invention relates to a separator plate for an electrochemical system, comprising a first and a second plate, which are essentially congruently arranged on top of one another. The first and/or second plates furthermore include at least one elongated projection, which protrudes on opposite sides from a plate plane of the separator plate and extends along the plate plane from an outer edge to an interior of the separator plate so that the projection of the first plate and/or the projection of the second plate, if necessary together, form a receptacle for a connector pin. The projection of the first plate or the projection of the second plate includes an indentation directed toward the respective opposite plate for fixing the connector pin in the receptacle in a force-fit and/or form-locked manner.
