摘要： To prevent the occurrence of cracking in a glass sealing member caused by, for example, thermal cycle or heat shock. An electrochemical reaction unit includes a unit cell; a separator bonded to a peripheral portion of the unit cell by means of a bonding member containing a brazing material; and a glass sealing member which is in contact with both the surface of the separator and the surface of the unit cell, thereby sealing between an air chamber and a fuel chamber. The separator has a first flat portion approximately parallel to a second direction perpendicular to a first direction; a second flat portion approximately parallel to the second direction; and a connection portion having a portion whose position in the first direction is different from that of the first flat portion and the second flat portion and connecting the first flat portion and the second flat portion.

摘要： An object is to restrain cracking and strain of interconnectors. Each interconnector-electrochemical reaction unit cell composite body includes an electrochemical reaction unit cell and an interconnector. The interconnector has a plurality of combinations of protrusions protruding in the first direction and recesses provided on a side opposite the protrusions in the first direction and being concave toward the protrusions. At least one of the plurality of combinations is configured such that, as viewed in the first direction, the bottom of the recess is located on the side toward the open end of the recess with respect to the proximal end of the protrusion, and in a section parallel to the first direction, the recess is located within the range of the width t2 of the protrusion in the second direction orthogonal to the first direction, and the width t1 of the recess in the second direction is smaller than the width t2 of the protrusion.

摘要： The present invention improves sealing of a combustion chamber or an air chamber by a sealing member. This fuel cell stack is provided with multiple power generation units, and is fastened with multiple fastening members. Each of the power generation units includes a single cell and a sealing member that is nipped between two other members to seal either a combustion chamber or an air chamber. The surface roughness Ra of a surface that is of the sealing member included in at least one of the power generation units and that opposes one of the two other members is not greater than 3.0 µm.
