<P>PROBLEM TO BE SOLVED: To provide an internal analytical apparatus for a fuel cell by which the internal state of the fuel cell is analyzed in a state that the fuel cell provided with a membrane electrode bonded body containing a solid polymer electrolyte membrane, an anode catalyst layer and a cathode catalyst layer generates electricity. <P>SOLUTION: The internal analytical apparatus for the fuel cell comprises transmission means 10, 21, 22, 23 by which probe light 41 and probe light 42 are transmitted in parallel to the bonding face of the solid polymer electrolyte membrane to the anode catalyst layer and the cathode catalyst layer with reference to the electrolyte membrane, detection means 31 by which absorption spectrum data on the probe light transmitted through the electrolyte membrane is detected and an analytical means which analyzes the absorption spectrum data so as to quantitatively calculate the amount of water molecules at the inside of the electrolyte membrane. The amount of the water molecules can be quantitatively grasped on the basis of an absorption peak of the absorption spectrum data, and the internal state of the fuel cell can be analyzed. <P>COPYRIGHT: (C)2003,JPO |
