PROBLEM TO BE SOLVED: To provide a fuel cell capable of solving a problem of gas transmission which has conventionally concentrated in an anode side separator and making a fuel cell stack compact. SOLUTION: (1) This fuel cell has an anode side separator 18A1 having a fuel gas passage 27 on its one surface and a coolant passage 26 on the other, and a cathode side separator 18A2 having an oxidizing gas passage 28 on its one surface and the coolant passage 26 on the other. In this fuel cell, a quantity of gas transmitting in the anode side separator 18A1 is adjusted to be not more than the quantity of gas transmitting in the cathode side separator 18A2 . (2) The thickness th of the anode side separator 18A1 at the bottom surface of the fluid passage is made mutually different from the thickness ta of the cathode side separator 18A2 at the bottom surface of the fluid passage. (3) They are set th>ta. |
