摘要： Provided is a droplet dispensing device having a nonconductive capillary nozzle. The droplet dispensing device comprises: a nonconductive capillary nozzle disposed in a downward position; a pump connected with the nonconductive capillary nozzle through a hermetically sealed fluid tube and generating a negative pressure to decrease the influence of gravity on a solution within the nonconductive capillary nozzle and the fluid tube; and an open circuit voltage supplier applying a voltage to the solution. The droplet dispensing device supplies the solution by capillary force to regularly maintain the shape of a droplet surface in the tip of the nonconductive capillary nozzle without using a separate driving device.

摘要： The volume of liquid that remains in a liquid storage is calculated by measuring capacitances between several pairs of metal plates attached to each of several corresponding faces of the liquid storage and by combining liquid volumes corresponding to the capacitance based on the current position of the liquid storage. Such a method of measuring the volume of liquid can be used to measure the amount of fuel that remains in a fuel cell system.
