Patent abstract
A capacitance fuel volume measuring apparatus for a fuel cell is disclosed. The apparatus utilizes two electrode boards disposed in a fuel tank and an elastic element to perform calculation of the fuel volume in the fuel tank. The apparatus includes a structure disposed in the fuel tank and a control unit. The structure in the fuel tank includes two electrode boards and an elastic element, which maintains the liquid level of the fuel in a level and transmits essential data corresponding to the distance between the two electrode boards to the control unit for calculation such that the control unit may obtain the volume of the fuel in the fuel tank.
