Abstract
PURPOSE:To enable accurate measurement of the fuel concentration of a fuel cell, by introducing electrolyte of a measured fuel cell into another fuel cell of a small capacity, detecting the fuel concentration and the temperature of the electrolyte introduce, being followed by correcting the concentration detecting signal according to the temperature detecting signal. CONSTITUTION:A body 11 is partitioned with a diaphragm 12 into an air-electrode chamber 13 and a fuel-electrode chamber 14, where an air electrode 15 and a fuel electrode 16 are located in parallel to one another. Electrolyte of a measured liquid- fuel cell which contains fuel is introduced into the fuel-electrode chamber 14 through an opened inlet 17 facing to introduction path 10. The temperature of the measured electrolyte inroduced into the fuel-electrode chamber 14 is always detected by either a thermocouple or thermistor 21 which is installed within a projection 20 protruding toward the fuel-electrode chamber. A great resistance 24, the voltage across which is measured as an output signal of a sensor by a voltmeter 25, is connected to between the fuel electrode 16 and the air electrode 15 by means of lead wires 22 and 23.
