摘要： In a metal support mostly used for a metal-supported solid oxide fuel cell (SOFC), a SOFC system that improves the power generation efficiency by allowing a gas to smoothly flow into or flow out from the through-holes is achieved. A metal support is formed in a plate shape as a whole and has a plurality of through-holes penetrating from a front surface on which an electrode layer is provided to a back surface, and the metal support has inclined through-holes, as the through-holes each of which has a central axis inclined with respect to a thickness direction.

摘要： Provided is a radiative cooling device that provides coloration of the radiative surface while maximally avoiding reduction in its radiative cooling performance due to absorption of solar light. An infrared radiative layer for radiating infrared light from a radiative surface and a light reflective layer disposed on the side opposite to the presence side of the radiative surface of the infrared radiative layer are provided in a mutually stacked state. The light reflective layer is arranged such that a first metal layer made of silver or silver alloy and having a thickness equal to or greater than 10 nm and equal to or less than 100 nm, a transparent dielectric layer and a second metal layer reflecting light transmitted through the first metal layer and the transparent dielectric layer are stacked in this order on the side closer to the infrared radiative layer. The transparent dielectric layer has a thickness that causes a resonance wavelength of the light reflective layer to be a wavelength included in wavelengths equal to or greater than 400 nm and equal to or less than 800 nm.

摘要： When a product gas producing operation is stopped, a purge operation is executed in which steam purge processing and product gas purge processing are sequentially performed. The steam purge is supplying, instead of a source gas, a product gas from a product gas tank to a reformer using a compressor, and supplying a reformed gas from a reforming processing unit to a plurality of adsorption towers, which perform a pressure swing adsorption operation, while the reformer is heated by a heating burner and steam is supplied to the reformer. The product gas purge is supplying the product gas from the product gas tank to the reformer using the compressor, and supplying the product gas from the reforming processing unit to the plurality of adsorption towers, which perform the pressure swing adsorption operation, while the supply of the steam is stopped and the heating of the reformer is maintained.
