Abstract: Separator plate for stacking fuel cells of the molten-carbonate type, provided with openings for fuel inlet and fuel outlet and for inlet and outlet of oxidizing agent, the gas passages through the separator plate having a spring characteristic as a result of choosing a suitable profile therefore and as a result of a frame-type spring which is disposed around the active cell assembly, which frame-type spring contains built-in components for conveying the process gases, and the profile of the frame spring is matched to the spring characteristic of the gas passage.
