PROBLEM TO BE SOLVED: To provide a fuel cell capable of well discharging water generated on a reaction gas flow passage side, and possible to be made compact successfully.SOLUTION: A surface 12a of a cathode side metal separator 12 structuring a fuel cell 10 is formed with an oxidizer gas flow passage 30 communicated with an oxidizer gas inlet communication hole 28a and an oxidizer gas outlet communication hole 28b. The cathode side metal separator 12 is provided with a plurality of continuous linear guide projections 40a and 40b projecting from intermediate height parts 38a and 38b toward the oxidizer gas flow passage 30 side to structure continuous guide flow passages 42a and 42b. Each linear guide projections 40a and 40b is continuously connected to an end of a straight flow passage projection 34b forming a straight flow passage 34a, and has bending parts 41a and 41b, and is set at a length different step by step. |
