<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of uniformizing distribution of face pressure in a cell face. <P>SOLUTION: (1) The fuel cell comprises an anode side separator 18A having a plurality of ribs 34 different in size from each other on a fuel gas passage, and a cathode side separator 18B having a plurality of ribs 34 different in size from each other on an oxidizer gas passage, and the ribs 34 of the anode side separator and the ribs 34 of the cathode side separator are arranged so that the distribution of the area of overlapped part becomes uniform on a cell face. (2) The short ribs 34S of the anode side separator 18A and the short ribs 34S of the cathode side separator 18B are overlapped at whole face of respective short ribs, and the long ribs 34L of the anode side separator 18A and the long ribs 34L of the cathode side separator 18B are overlapped only at a part of respective long ribs, and the area of respective overlapped parts of the long ribs are arranged so as to become almost the same as the area of the overlapped part of the short ribs. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
