SUPPORTING BODY FOR SOLID ELECTROLYTE TYPE FUEL CELL, UNIT CELL FOR SOLID ELECTROLYTE TYPE FUEL CELL AND MANUFACTURE OF SUPPORTING BODY FOR SOLID ELECTROLYTE TYPE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To lessen the amount of gas leakage at an inter-connector, and enhance the generating capacity of a unit cell in the solid electrolyte type fuel cell of a cylindrical type and the like. SOLUTION: The supporting body 13 of the solid electrolyte type fuel cell is provided with an electrode body 14 extended along the longer direction of the supporting body, and with an inter-connector 14 extended along the longer direction of the supporting body 13. When the cross sectional surface of the supporting body 13 is viewed from above, it can be seen that the paired end parts in the width direction of the electrode body 14 are integrated with the paired end parts in the width direction of the inter-connector 15 respectively. The thickness of the inter-connector 15 is 1 to 5mm, and the porosity of the inter-connector 15 is 1 to 8%.
