摘要： An anode (11a) and a cathode (11b) are provided on either side of an electrolyte membrane (11). A first separator (2) is disposed so as to face the anode (11a), and a second separator (3) is disposed so as to face the cathode (11b). A first sealing member (12) is disposed between the electrolyte membrane (11) and the first separator (2), and a second sealing member (13) is disposed between the electrolyte membrane (11) and the second separator (3). The cross-sectional shape or rubber hardness of the sealing members (12, 13) is varied according to a deformation amount generated in the electrolyte membrane (11) by a sealing reactive force. More specifically, in a site where the deformation amount of the electrolyte membrane (11) is large, either the contact area between the sealing member (12) and the electrolyte membrane (11) is increased, or the rubber hardness of the sealing member (12) is reduced. In so doing, deformation of the electrolyte membrane (11) caused by the sealing reactive force is suppressed, and the sealing performance of a fuel cell (10) is improved.

摘要： A cell of a fuel cell includes a membrane electrode assembly, and metal first and second separators which sandwich the membrane electrode assembly to form gas flow paths disposed on each side of the membrane electrode assembly. A back surface of the first separator and a back surface of the second separator, the first separator and the second separator being included in adjacent cells, are in contact with each other, thereby forming a temperature-control medium flow path between the first separator and the second separator. In the first separator and the second separator, corrosion-resistant coating layers are provided only on reaction-side surfaces of the first separator and the second separator, the reaction-side surfaces facing the membrane electrode assembly, and portions where the back surface of the first separator is in contact with the back surface of the second separator are joined by welded portions.
