<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of assembling unit cells highly accurately and easily in a simple as well as economical structure. <P>SOLUTION: A unit cell 12 is provided with an electrolyte membrane-electrode structural body 14, and a cathode side separator 16 and an anode side separator 18 pinching the electrolyte membrane-electrode structural body 14. The cathode side separator 16 is integrally provided with a plurality of positioning pin members 42 on a separator face. The positioning pin members 42 are provided with four elastic piece parts 44 arrayed on concentric circles, and each of the elastic piece parts 44 has an inclined face 44a inclining outward in a direction parting from the cathode side separator 16. The anode side separator 18 is provided with a positioning hole part 46 for positioning to insert the positioning pin member 42, at a position corresponding to each of the positioning pin member 42 along a lamination direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
