| 内容: | The invention relates to a electrically conductive steel-ceramic connection comprising a steel interconnector and an electrically conductive ceramic joining layer arranged thereon. The interconnector comprises a ferritic steel containing Cr in a quantity ranging from 18 to 24% by weight. The ceramic layer contains perovskite of a formula Ln1-x Srx Mn1-yCoyO3-delta or Ln1-xSrxFe1-yCoyO3-delta, wherein 0,1 <= X <= 0,4, 0,1 <= y <= 0,6, 0 <= delta <= x/2 and Ln = La-Lu. The inventive steel-ceramic connection is usable for a high-temperature fuel cell and regularly exhibits good adhesive properties and a low transition resistance (initial transition resistance R approximately equal to 0,01 ohm cm<2>). Said steel-ceramic connection makes it possible to advantageously introduce a ferritic steel into high-temperature fuel cells. The inventive method for producing said steel-ceramic connection consists in pre-treating an inserted ceramic powder exhibiting good sinterability during an assembly process and during the fuel cell operation. |
