Abstract
An electrochemical reaction unit including 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.
