A concentration detector is adapted to detect the concentration of a liquid fuel in a container. The concentration detector comprises a rotating mechanism positioned underneath the level of the liquid fuel and having a rotational center. A first float having a specific gravity less than the specific gravity of the liquid fuel, a volume equivalent to 'V' and a mass equivalent to 'M'. The distance between the mass center of the first float and the rotational center is &#x201c;L&#x201d;. A second float connected with the first float and having a specific gravity less than the specific gravity of the liquid fuel, a volume equivalent to &#x201c;V&#x201d; and a mass equivalent to &#x201c;r*M&#x201d;. The distance between the mass center of the second float and the rotational center is &#x201c;L. The mass center of the second float, the rotational center and the mass center of the first float constitute an included angle of 120&#xb0;. A third float connected to the first float and the second float and having a specific gravity less than the specific gravity of the liquid fuel, a volume equivalent to &#x201c;V&#x201d; and a mass equivalent to &#x201c;r*M&#x201d;. The distance between the mass center of the third float and the rotational center is &#x201c;L. The mass center of the third float, the rotational center and the mass center of the second float constitute an included angle of 120&#xb0;. Thereby the variation in the concentration of the liquid fuel is acquired by inspecting the change in the rotational direction of the rotating mechanism.

Concentration detector

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.
