    Abstract: A fluid container includes a first metallic member, a second metallic member, an adherence part, a first interface, and a second interface. The first metallic member contains chromium. The second metallic member contains chromium. The adherence part is made of an oxide containing chromium as a primary component. The adherence part adheres the first and second metallic members to each other. The first interface is provided as an interface between the first metallic member and the adherence part. The second interface is provided as an interface between the second metallic member and the adherence part. The first interface includes a first slant portion. The first slant portion slants with respect to an in-plane direction of the first metallic member.

    Abstract: A chromium alloy container has an internal space. The reducing gas container includes a first metal member, a second metal member, and a sealing portion sealing a gap between the first metal member and the second metal member. The sealing portion includes a first bonding portion integrated with the first and second metal members, and a second bonding portion sandwiched between the first and second metal members and disposed on an internal space side of the first bonding portion. The first bonding portion is constituted by a metal material. The second bonding portion is constituted by a crystalline metal oxide.

    Abstract: A chromium alloy container has an internal space. The chromium alloy container includes a first alloy member constituted by an alloy containing chromium, a second alloy member constituted by an alloy containing chromium, and an interposing portion interposed between the first alloy member and the second alloy member. The interposing portion includes an oxide adhesion layer constituted by an oxide containing chromium as a main component, and a metal connection portion embedded in the oxide adhesion layer and connecting the first alloy member and the second alloy member to each other.

    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; a first electrode layer disposed on the gas diffusion layer; a second electrode layer; and an electrolyte layer disposed between the first electrode layer and the second electrode layer. In a plan view of the principal surface, at least a portion of an outer edge of the gas diffusion layer has a wave shape in which a peak portion and a valley portion are alternately continuous with each other.

    Abstract: The present fluid container includes a first metallic member, a second metallic member, an adherence par, a first interface, and a second interface. Each of the first and second metallic members contains chromium. The adherence part is made of an oxide containing chromium as a primary component. The adherence part adheres the first metallic member and the second metallic member to each other. The first interface is provided as an interface between the first metallic member and the adherence part. The second interface is provided as an interface between the second metallic member and the adherence part. The first interface includes a first wavy portion. The first wavy portion repeatedly winds in a thickness direction. The first wavy portion extends along an outer peripheral edge of the first metallic member.
