<P>PROBLEM TO BE SOLVED: To provide a device for measuring electromotive force distribution in a fuel cell, with which partial electromotive force of total electromotive force obtained from the whole surface of the fuel cell can be exactly reproduced, and to provide a method for measuring the electromotive force distribution in the fuel cell, by which partial electromotive force of the total electromotive force obtained from the whole surface of the fuel cell can be exactly reproduced. <P>SOLUTION: The device 40 for measuring the electromotive force distribution in the fuel cell includes: a plurality of probe pins 35 which are dispersively arranged in contact with a surface of a separator 3 on a fuel electrode side; a reference probe pin 35a that is singly arranged; a potential distribution measuring section 44 which detects respective potential differences between the reference probe pin 35a and the plurality of the probe pins 35; a lead wire 3b on the fuel electrode side and a lead wire 6a on an air electrode side which are taken out for getting output of the fuel cell 10 via a route different from the reference probe pin 35a or the potential distribution measuring section 44; and a personal computer 42 which computes the electromotive force distribution on the surface of the separator 3 on the fuel electrode side on the basis of the respective potentials between the reference probe pin 35a and the plurality of the probe pins 35 measured by the potential distribution measuring section 44. <P>COPYRIGHT: (C)2007,JPO&INPIT |
