CELL FOR FUEL CELL, METHOD FOR PRODUCING THE SAME, AND GAS CHANNEL STRUCTURE FOR FUEL CELL

摘要

A cell (10) for a fuel cell, comprising a membrane electrode assembly (18), expanded moldings (20) that are laminated to both surfaces of the membrane electrode assembly (18) and form gas channels, and separators (22) that are laminated to the gas channel structures (20) and separate the gases between adjacent cells, wherein each of the expanded moldings (20) comprises a gas channel substrate (24) formed from a metal material such as a titanium material or a stainless steel, a conductive layer (26) that is formed from a conductor such as gold (Au) on a contact portion (25) of the gas channel substrate (24) that contacts the membrane electrode assembly (18) or the separator (22), and a hydrophilic layer (28) that is formed from a hydrophilic material such as a titanium oxide on the gas channel surface of the gas channel substrate (24).
