Patent ID: 7604670

Claim:
A method for producing an electrolyte-electrode joined assembly comprising a solid electrolyte interposed between an anode and a cathode, said method comprising: manufacturing constitutive particles of one said anode and said cathode by a spray drying method or a rolling granulation method: manufacturing a compact with said constitutive particles by press forming at a press pressure of 25 to 120 MPa such that a porosity of the compact becomes 40% to 70%, and then heating said compact; providing said solid electrolyte on one end surface of said compact and then mutually sintering said compact and said solid electrolyte to prepare a sintered product; and providing other of said anode and said cathode on said solid electrolyte of said sintered product, wherein said one of said anode and said cathode prepared with said compact is manufactured as a portion of said sintered product and includes said constitutive particles bonded to one another in an aggregated state and pores which communicates with each other three-dimensionally and of which two-dimensional cross sections are not perfect circles, such that a porosity of the sintered product is 10% to 50% by volume.
