PROBLEM TO BE SOLVED: To provide a potential measuring device for a fuel cell capable of highly accurately measuring potential in a simple and economical configuration.SOLUTION: A potential measuring device 10 for a fuel cell is provided in an electrolyte membrane/electrode structure 14. The potential measuring device 10 comprises an anode-side reference electrode 51 and a cathode-side reference electrode 53, the anode-side reference electrode 51 installed in an anode electrode 22 and the cathode-side reference electrode 53 installed in a cathode electrode 24, and potential sensors 54, 56, 58, and 60 which are connected to the anode electrode 22 and measure each anode potential between themselves and the anode-side reference electrode 51. The anode-side reference electrode 51 is integrally provided with the potential sensors 54, 56, 58, and 60 via a base material 62a. |
