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.
