PURPOSE:To improve the cell performance and durability by using a platinum group element group regenerating catalyst loaded on a zirconia group carrier and a specific mixed alkaline carbonate electrolyte. CONSTITUTION:As a regenerating catalyst 7, is used a platinum group element group reforming catalyst loaded on a zirconia group carrier. As the zirconia carrier, is used a partially stabilized zirconia, and the yttria containing zirconia is preferable. As the platinum group element, are preferable rhodium and ruthenium. Further, as an electrolyte, is used a two-component substance consisting of lithium carbonate and sodium carbonate, or a mixed substance consisting of the above-described two-component substance as main component and other carbonate compounded. The groove of a fuel gas passge 6 of a regeneration reactor 1 is filled with the catalyst 7, and a Ni porous plate 2 impregnated with the electrolyte and an electrolyte holding plate 3 are laminated, and sealed by a sealing plate 4. Accordingly, performance can be maintained for a long period. |
