ABSTRACT:
A fuel gas supply channel connecting a fuel gas supply passage and a fuel gas inlet are provided in a separator, a channel lid member, and a circular disk member. A filter mechanism for filtering a fuel gas supplied from the fuel gas supply passage to a channel unit is provided in the fuel gas supply channel. The filter mechanism has a plurality of holes, and the cross sectional area of the opening of the hole is smaller than the cross sectional area of the opening of the fuel gas inlet.
