PROBLEM TO BE SOLVED: To supply fuel gas to the whole area of a fuel gas passage uniformly and well by preventing the fuel gas, especially a lightweight gas, from flowing to the upper side of the fuel gas passage in large quantities.SOLUTION: A fuel gas is supplied from a fuel gas supply communication hole 20a to a fuel gas passage 34 provided on the surface 16a of an anode side separator 16 constituting a fuel cell. The fuel gas supply communication hole 20a and the flow direction upstream side of the fuel gas passage 34 are interconnected by inlet coupling passages 38a. An uppermost inlet coupling passage 38ae inclines more downward than other inlet coupling passages 38a, and an inlet coupling branch passage 39 inclining upward is provided in the way of the uppermost inlet coupling passage 38ae. |
