ABSTRACT:
The present invention is to provide a measurement apparatus of measuring fuel capacity used in fuel cell system; the measurement apparatus comprises a sensor device, a resistor, an A/D converter and a controller. The sensor device comprises a first electrode and a second electrode and accommodated in fuel storage and/or fuel flow layer to detect the fuel capacity of the anode, the second electrode connects to a low level voltage, one terminal of the resistor connects to the first electrode, the other terminal electrically connects to a high level voltage. The input terminal of the A/D converter connects to the first electrode and the first terminal of the resistor to input a measuring analog voltage, and also converts into a measuring digital voltage, the controller connects to the A/D converter to input measuring digital voltage and converts into the liquid level of the anode fuel in the fuel storage and/or fuel flow layer.
