New solutions and materials for Molten Carbonate Fuel Cells

This paper deals with an investigation on new materials, treatments and procedures suitable for Molten Carbonate Fuel Cells (MCFC). Investigation was carried out by manufacturing a single cell facility (SCF) which was used as test bench. SCF is constituted by: - a single MCFC; - exhaust and inlet manifolds; - a frame for cell elements stacking; - a heating system. Cell frame was covered by thermal insulation material. High temperatures sensors were installed into heating system, cathodic and anodic sections. By means of SCF the following components were tested: - electrolyte matrices based on tape-casting and injection moulding formation procedures; - cathodes and anodes obtained by tape-casting formation procedures; - new materials for electrodes mechanical support. Results showed that: - dewaxing is quicker and less carbonic residues occur on matrices obtained by injection moulding. - the proposed original materials for electrodes support provide high mechanical resistance.
