<P>PROBLEM TO BE SOLVED: To provide a separator for a fuel cell operating at high temperature of 100°C or higher capable of preventing problems of an increase of pressure loss at a cathode separator and increase of pressure difference between an anode and a cathode in case of using a separator for the PEFC operating at high temperature having operation temperature of 100°C or higher, capable of improving energy efficiency of a fuel cell by reducing blower loss and improving life by reducing a stress burdened on an MEA. <P>SOLUTION: On the separator of the high temperature operation PEFC of 100°C or higher, cross section of a flow passage at outlet of the cathode separator is larger than that at inlet thereof. By the above the pressure loss at nearing area of outlet of the separator can be reduced. <P>COPYRIGHT: (C)2007,JPO&INPIT |
