    摘要： There are provided a solid oxide fuel cell system comprising (a) a solid oxide fuel cell stack, (b) a preliminary reformer for removing hydrocarbons having two or more carbon atoms from a hydrocarbon fuel by converting the hydrocarbons having two or more carbon atoms into methane, hydrogen, and carbon monoxide, and (c) an integrated heat exchanger for catalytic combustion for heating either air or fuel, or both the air and fuel, to be guided to the solid oxide fuel cell stack, by use of a combustion gas formed by combusting discharged fuel with the use of discharged air, wherein component equipment described above are disposed in an adiabatic vessel and the integrated heat exchanger for catalytic combustion for use in the solid oxide fuel cell system. With the invention, an advantage of the preliminary reformer in combination with that of the integrated heat exchanger for catalytic combustion can be obtained, and heat loss of the SOFC system is eliminated or reduced as much as possible. In addition, with the integrated heat exchanger for catalytic combustion according to the invention, since air and / or fuel, to be fed to the SOFC stack, can be heated by controlling the maximum temperature achieved thereof, it is quite useful as an heat exchanger for an SOFC with operation temperature on the order of 850 DEG C or lower, particularly, for a supported membrane type SOFC, and further, the same is quite useful in making up an SOFC system because an inexpensive material can be used as a constituent material of a component equipment of the system, the system in whole can be reduced in size, and so forth.

    摘要： A fuel electrode of solid electrolyte type fuel cells which is made of a cermet composed of yttria-stabilized zirconia containing a transition metal dissolved therein and nickel (Ni) or a cermet composed of yttria-stabilized zirconia containing a transition metal dissolved therein, Ni and cerium oxide containing a divalent or trivalent metal dissolved therein can be prepared by adding a solution of an organoyttrium compound and a solution of an organic transition-metal compound to a solution of an organozirconium compound to prepare a mixed solution of organometallic compounds containing zirconium, yttrium and transition metal as the metal components, adding NiO powder or a powder mixture of NiO powder with cerium oxide powder containing a divalent or trivalent metal oxide dissolved therein to the above mixed solution to prepare a slurry, and subjecting this slurry to hydrolysis, polycondensation, pyrolysis, annealing and reduction successively. This fuel electrode can be formed on a solid electrolyte layer by screen process printing.
