A fuel cell stack has a plurality of fuel cells (14), separators (16), (18) sandwiching each of the fuel cells (14), and first and second end plates (58), (60) disposed on respective opposite ends of the plurality of fuel cells (14). A fastening structure (10) incorporated in the fuel cell stack has a liquid chamber (62) disposed on an outer surface (58a) of the first end plate (58), a silicone oil (64) filled in the liquid chamber (62), and a pressurizing mechanism (66) disposed on an outer surface (60a) of the second end plate (60), for pressing the fuel cells (14) toward the first end plate (58). The plurality of fuel cells (14) is given a uniform surface pressure, and can be reduced in weight and made compact. <IMAGE> |
