摘要： An electrode of a solid oxide fuel cell has a skeleton (11) constituted of a porous sintered compact having a three dimensional network structure, the porous sintered compact being made of an oxide ion conducting material and/or a mixed oxide ion conducting material; grains (12) made of an electron conducting material and/or a mixed oxide ion conducting material are adhered onto the surface of the skeleton; and the grains are baked inside the voids (13) of the porous sintered compact under the conditions such that the grains are filled inside the voids. The electrode drastically improves the electrode properties and alleviates the thermal shock and the thermal strain to a great extent. It is preferable that the electrode is used in the form such that the electrode is formed to be integrated with the electrolyte on one surface or on both surfaces of an oxide ion conducting, dense solid electrolyte layer.

摘要： Provided is a power generation cell for a solid electrolyte fuel cell, in which a lanthanum gallate-based electrolyte is used as a solid electrolyte. Use of alternative energy for replacing petroleum can be promoted and it is possible to use waste heat using the solid electrolyte fuel cell, thus the solid electrolyte fuel cell is watched in views of resource nursing and the environment. The power generation cell is typically operated at 800 to 1000° C. However, currently, the power generation cell, which is operated at 600 to 800° C. by using the lanthanum gallate-based electrolyte, is suggested. Since a current power generation cell has a large size and has an insufficient output, there are demands for size reduction and high output. In the power generation cell, Sm-doped ceria particles are separately attached to a surface of porous nickel having a network frame structure. The demands are satisfied by using the anode.
