Abstract
Auxiliary seals are provided on a surface of a first metal separator, between load receivers and an oxygen-containing gas supply passage, a fuel gas supply passage, an oxygen-containing gas discharge passage, and a fuel gas discharge passage, in relatively wide areas. The cross sectional shape of the auxiliary seal is the same as those of a flow field seal and ring-like seals, and the auxiliary seals are formed independently from the flow field seal and the ring-like seals.
