The invention relates to a bipolar separator (17) including a first (33) and a second (35) polar plate each comprising an inner surface and an outer surface in which at least one distribution channel (53, 55) is formed, the channels formed in the outer surfaces of the first and the second polar plate enabling fuel and oxidizer, respectively, to flow. The bipolar separator further includes an inner layer (29) provided to be sandwiched and compressed between the substantially planar inner surfaces of the first (33) and the second (35) polar plate, so as to form a laminated structure. The inner layer is formed by a perforated sheet comprising a group of through-grooves that form branchless channels, the ends of which lead, respectively, to two manifolds such that the coolant is able to flow between the first (33) and the second (35) polar plate.

An object of the invention is to increase the output power of a solid oxide fuel cell by making a lower electrode layer porous so as to form a three-phase interface and reducing a thickness of a solid electrolyte layer to 1 micrometer or less. A fuel cell according to the invention includes a first electrode layer at a position where an opening formed in a board is covered, and a solid electrolyte layer having a thickness of 1000 nm or less. At least a part of a region of the first electrode layer covering the opening is porous (see FIG. 5).

An alloy member includes a base member that includes a plurality of recesses in a surface and is constituted by an alloy material containing chromium, a plurality of embedded portions that are respectively disposed in the plurality of recesses, and a coating layer that covers the base member and is connected to the plurality of embedded portions. An average value of actual lengths of line segments of the plurality of embedded portions is longer than an average value of straight lengths of straight lines of the plurality of embedded portions in a cross-section of the base member along a thickness direction of the base member. The average value of the actual lengths is 1.10 times or more the average value of the lengths of the straight lines.
