Ferritic material has more than 68 weight % Fe and general impurities, 22 to 32 weight % Cr, 1 to 10 weight % Mo and 0.01 to 0.1 weight % yttrium and/or rare earth metal and/or their oxides. Solid state electrolyte is cerium oxide, doped with Gd, Ca, Sm and/or Y, or electrolyte is of zirconium oxide doped with Y, Ca, Sc and/or Yb. Near end contours of accumulator is made by powder metallurgy and ferrite material additionally has 0.1 to 3 weight % Nb, Ti, Ni and/or Mn. |
