CONCENTRATION DETECTOR, AND FUEL SUPPLY TANK USED FOR LIQUID FUEL CELL

摘要

PPROBLEM TO BE SOLVED: To provide a concentration detector and a fuel supply tank used for a liquid fuel cell. PSOLUTION: This concentration detector is one kind of concentration detector and is used for detecting a concentration of liquid fuel in a container. The concentration detector includes a rotary mechanism. The rotary mechanism is provided under a liquid level of the liquid fuel, and is rotatable by an angle on an X-Y plane. The rotary mechanism includes at least three or more of floating objects. The floating objects are connected each other, and each specific gravity of the floating objects is not higher than a specific gravity of the liquid fuel, and the floating objects are brought into a stationary condition under the liquid level of the liquid fuel, because the floating objects are provided based on a torque balance equation F(, )=0. The rotation angle of the rotary mechanism is detected when the concentration of the liquid fuel is varied thereby, and the specific gravity of the liquid fuel is found based on the balance equation F(, )=0, so as to be reduced to the concentration of the liquid fuel.
