    Abstract: An electrochemical cell includes a metal substrate having a principal surface and a plurality of connecting holes formed in the principal surface, and a cell body disposed on the principal surface. The cell body has a gas diffusion layer disposed on the principal surface, the gas diffusion layer being electrically conductive, and a first electrode layer disposed on the gas diffusion layer; a second electrode layer. The gas diffusion layer includes a first portion sandwiched between the principal surface and the first electrode layer. The first portion has a gas flow path having a length equal to 20% or more of a total thickness of the first portion in a thickness direction thereof in a cross-section of the first portion along the thickness direction.

    Abstract: A possibility is suppressed that a gripping position of a gripping member is moved by an external impact and a gripping force is reduced. In a gas sensor according to one aspect of the present invention, a gripping member that grips a portion covered with a tube in an outer peripheral surface of a cylindrical body such that the tube protrudes to a side opposite to an open end of the cylindrical body grips an outer peripheral surface covered with the tube of a caulked portion closest to the open end among one or more caulked portions formed in the cylindrical body.

    Abstract: A reactor module includes a pre-reactor and a membrane reactor disposed downstream of the pre-reactor. The membrane reactor includes a separation membrane. In the pre-reactor, an intermediate gas is generated from a source gas containing hydrogen and carbon oxide. The intermediate gas contains a liquid fuel, water vapor, and residual source gas. In the membrane reactor, the liquid fuel and water vapor are generated from the residual source gas. The separation membrane allows the water vapor contained in the intermediate gas and a product generated from the residual source gas to pass therethrough.

    Abstract: A honeycomb structure includes: an inner peripheral wall; an outer peripheral wall; and partition walls disposed between the inner peripheral wall and the outer peripheral wall, the partition walls defining a plurality of cells each extending from a first end face to a second end face. In a cross section orthogonal to an extending direction of the cells, the partition walls include one or more first partition walls extending in a radial direction. The inner peripheral wall and the outer peripheral wall have an average thickness of 0.1 mm or more, and a thickness variation coefficient of 1.0 or less, represented by the following equation (1):


    the thickness variation coefficient=a standard deviation of the thicknesses of the inner peripheral wall and the outer peripheral wall/an average thickness of the inner peripheral wall and the outer peripheral wall  (1).
