A fuel cell device with a compound power supply is disclosed, which comprises a bipolar fuel cell board and an auxiliary power supply. The bipolar fuel cell board includes at least one fuel cell unit. The auxiliary power supply is disposed on the bipolar fuel cell board and/or on an intermediate substrate sandwiched within the fuel cell device, and is connected to the fuel cell units. Stable power is output due to the combination of power from the fuel cell units and the auxiliary power supply.

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

A concentration detector is disclosed, which is adapted to detect a concentration of a liquid fuel in a container. The concentration detector includes a rotating means positioned underneath a level of a liquid fuel and rotatable at an angle &#x3b8; on a X-Y plane. The rotating means includes at least three floating objects connected with each other. Each floating object has a specific gravity less than a specific gravity of the liquid fuel &#x3c1;. The floating objects are balanced according to a torque equation, F(&#x3b8;,&#x3c1;)=0, such that the rotating means is still under the level of the liquid fuel. While a concentration of the liquid fuel is changed and the angle &#x3b8; of the rotating means is detected, the specific gravity of the liquid fuel &#x3c1; is obtained from the torque equation, F(&#x3b8;,&#x3c1;)=0, and thereby computing the concentration of the liquid fuel.
