Disclosed are a fuel cell which has a film electrode assembly (107), comprising, in succession, a cathode, an electrolyte film (102) and an anode, and an anode current collector layer (108); and a fuel cell stack which uses the fuel cell. The anode current collector layer (108) has a pair of first walls (120) which are provided opposite each other along the two sides of the collector. The film electrode assembly (107) is fitted between the pair of first walls (120) so that the anode is opposite the anode current collector layer (108). Preferably, a pair of second walls (116) formed on the pair of first walls (120) is provided. |
