Abstract

Performances of an original cylindrical Molten Carbonate Single Cell are here reported. The cell main peculiarity is the original architecture which involves both elements geometry and gases arrangements. High benefits may be obtained by the proposed configuration. Cylindrical elements may be easily obtained by injection printing; this is a moulding technique which is conveniently used for large scale productions because of time and cost advantages. Moreover, cylindrical configuration produces lower heat losses because of high volume with respect to surface. Besides, sealing is enhanced and compression strain is kept uniform along cell surface. The original gases arrangement is attained by stacking circular holed thin steel rings. Tests were carried out to determine voltage/current characteristic at different conditions: with and without steam into cathodic compartment at several times along cell lifetime. It was also verified cell resuming performances when a temperature drop occurs. Maximum power density was evaluated for different conditions. Results suggest that the proposed cell design is a promising solution for FC uCHP applications because of performances, durability and low realisation costs. Actually a stack made by 13 single cells is under test.
