Abstract
A separator assembly for a fuel cell includes a first separator, a second separator, and a joined portion. In the joined portion, the first separator and the second separator are joined to each other through laser welding. The first separator includes a first surface that is intended to be opposed to the membrane electrode assembly. The first surface of the first separator includes an exposed portion where the base of the first separator is exposed. The second separator includes a second surface that is intended to be opposed to the membrane electrode assembly. A film including conductive particles is arranged on the entire second surface of the second separator. The joined portion is formed by irradiating the exposed portion of the first separator with laser.
