<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a unit cell for a fuel cell achieving excellent adhesive strength between layers in a small number of firing steps, and a unit cell for a fuel cell excellent in the adhesive strength between layers. <P>SOLUTION: A unit cell 1 for a fuel cell comprises a solid electrolyte layer 11, a fuel electrode layer 12 on one side of the solid electrolyte layer 11, and an air electrode layer 14 disposed on the other side of the solid electrolyte layer 11 with an intervention of an intermediate layer 13, and the air electrode layer 14 comprises a dense electrode layer 141 in contact with the intermediate layer 13, and a porous electrode layer 142 being in contact with the dense electrode layer 141 and more porous than the dense electrode layer 141. A method for manufacturing the unit cell 1 for a fuel cell comprises the step of firing a laminate 2 obtained by laminating a first layer 23 yet to be fired to become the intermediate layer 13, a second layer 241 yet to be fired to become the dense electrode layer 141, and a third layer 242 yet to be fired to become the porous electrode layer 142 in this order. <P>COPYRIGHT: (C)2013,JPO&INPIT |
