Title:
燃料電池スタックおよび燃料電池セパレータ並びにその製造方法
Document Type and Number:
Japanese Patent JP5343307
Kind Code:
B2
Abstract:
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.
