Abstract
A cell for a fuel cell, comprising a membrane electrode assembly, expanded moldings that are laminated to both surfaces of the membrane electrode assembly and form gas channels, and separators that are laminated to the gas channel structures and separate the gases between adjacent cells, wherein each of the expanded moldings comprises a gas channel substrate formed from a metal material such as a titanium material or a stainless steel, a conductive layer that is formed from a conductor such as gold on a contact portion of the gas channel substrate that contacts the membrane electrode assembly or the separator, and a hydrophilic layer that is formed from a hydrophilic material such as a titanium oxide on the gas channel surface of the gas channel substrate.
