    Abstract: The present invention provides a novel manufacturing method for a solid oxide fuel cell apparatus in which members of the apparatus are joined together with an adhesive, such as a ceramic adhesive. The method implements first and second types of drying and hardening steps. The first type of step may be called a workable hardening step and gives an assembly of members in the solid oxide fuel cell apparatus structural rigidity to go through assembling of the solid oxide fuel cell apparatus. The second type of step may be called a solvent elimination and hardening step and gives the assembled members property to withstand the operation temperature of the solid fuel oxide cell apparatus. The first type of step is performed at a first temperature lower than a second temperature at which the second type of step is performed. The second type of step is performed only after the first type of step is performed at multiple times.

    Abstract: An electrostatic chuck includes: an electrically-conductive base plate including a first part, a second part at an outer circumference of the first part, and a gas inlet path for introducing a cooling gas; a first electrostatic chuck part configured to clamp a wafer on the first part, including a ceramic dielectric substrate that includes an embedded first clamping electrode and at least one through-hole communicating with the gas inlet path; and a second electrostatic chuck part configured to clamp a focus ring on the second part, including a ceramic layer that includes at least one through-hole for introducing a cooling gas and that includes at least a first layer contacting the focus ring when the second electrostatic chuck part clamps the focus ring, in which the first layer is less dense than the ceramic dielectric substrate. Thereby, the electrostatic chuck can increase the device yield.

    Abstract: An object of the present invention is to provide a fuel cell preventing formation of a diffusion layer containing Ca and other elements, and having an excellent power generation performance at low temperature by preventing breakdown of a crystal structure of an electrolyte by firing. Disclosed is a solid oxide fuel cell which includes an inner electrode, a solid electrolyte, and an outer electrode, each sequentially laminated on the surface of a porous support. The porous support contains forsterite, and has a Ca element content of 0.2 mass % or less in terms of CaO in a surface region at the inner electrode side.
