PURPOSE:To improve the percentage of good products in a cell manufacturing process and ensure stability and reliability of a fuel cell over a long period. CONSTITUTION:A porous stabilizing ZrO2 sintered body which contains at least CaO, Y2O3 and/or Yb2O3 as stabilizer and has the content of Al and Si being 100-5000ppm in metal conversion is used for a fuel cell supporting tube. In this way, the supporting tube is excellent in its strength at the beginning and after used for a long period at a high temperature. |
