LAMINATED SINTERED BODY FOR ELECTROCHEMICAL CELL, ELECTROCHEMICAL CELL, AND MANUFACTURE OF LAMINATED SINTERED BODY FOR ELECTROCHEMICAL CELL

摘要

PROBLEM TO BE SOLVED: To suppress raising of an internal electric resistance on the junction critical surface or the like with a separator and an electrode, prevent peeling-off on the junction critical surface, and eliminate possibility of advancement of crack in the case where an electrochemical cell is subject to a cycle between power generation under high temperature and temperature fall. SOLUTION: A planar laminated sintered body 21A is made of an electrode 15A and a separator 16A. Gas flow paths 22A of plural columns are provided inside the laminated sintered body 21A, plural grooves 23A are formed on the critical surface side with the separator 16A of the electrode 5A, plural grooves 24A are formed on the critical surface with the electrode 15A of the separator 16A. Further, each gas flow path 22A is formed by means of both of the groove 23A formed on the electrode 15A and the groove 24A formed on the separator 16A.
