PURPOSE:To simplify wiring of a converter for sensor installed in a fuel cell and increase measuring accuracy with a sensor. CONSTITUTION:Analog signals outputted from sensors 6, which detect temperature and voltage, installed in a plurality of stacked cells of a power generating part 5 of a fuel cell is transmitted to an A/D converter 4 with lead-out wires 7. Analog signals are converted to digital signals by the A/D converter and transmitted to the outside of a cell accommodating tank 1 with an optical fiber 8. The power source of the A/D converter 4 is supplied from a part of the power generating part 5 of the fuel cell through a transmission line 9. In order that the power source is supplied from a part of the power generating part of the fuel cell, wiring of the transmission line 9 to the converter is made easy, and owing to using one optical fiber as the lead-out wire 8, insulation of the lead-out wire 8 in the portion where the wire 8 is led out from the tank 1 is simplified and measuring accuracy with the sensor 6 is improved. |
