<P>PROBLEM TO BE SOLVED: To prevent the erroreous combination of conductive separator plates when assembling a solid polymer fuel cell. <P>SOLUTION: The solid polymer fuel cell is formed by laminating a plurality of unit cells each of which comprises a membrane electrode assembly 11 where a pair of electrodes including catalyst layers are arranged on both sides of a proton exchange membrane, respectively, and a plurality of conductive separator plates 12, 14 and 16 which sandwich the membrane electrode assembly 11. C cuts are applied to corners of the conductive separator plates 12, 14 and the number of the C cuts in each conductive separator plate 12, 14 is different, and thus a difference of kinds in the conductive separator plates is distinguishable in appearance. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
