    • An electrochemical apparatus having a plurality of ceramic electrochemical cells, a plurality of gas feed members and a plurality of gas discharge members. The electrochemical cell has a first electrode contacting with a first gas, a solid electrolyte layer and a second electrode contacting with a second gas. A gas flow channel for flowing the first gas therethrough, a first through hole and a second through hole are provided in the electrochemical cell. The gas feed member is inserted into the first through hole, the gas discharge member is inserted into the second through hole. The adjacent gas feed members are airtightly coupled to each other thereby forming a gas feed channel, and the adjacent gas discharge members are airtightly coupled to each other thereby forming a gas discharge channel.

    • An SOFC unit cell 100 includes a fuel-side electrode 110, an electrolyte 120 stacked on the fuel-side electrode 110, and an oxygen-side electrode 130 stacked on the electrolyte 120. The fuel-side electrode 110 is formed of NiO and/or Ni and YSZ. The amount by volume of Ni and/or NiO is 35 to 55 vol. %, as reduced to Ni, on the basis of the entirety of the fuel-side electrode, and the amount by volume of YSZ is 45 to 65 vol. % on the basis of the entirety of the fuel-side electrode. The ratio of the mean particle size of YSZ (R2) to the mean particle size of Ni and/or NiO (R1); i.e., R2/R1, is 0.5 or more. Reduction treatment of the fuel-side electrode 110 after firing is carried out by supplying a reducing gas containing a reducing agent (hydrogen) in an amount of 4 to 100 vol. % at a high temperature of 800° C.
