摘要： Disclosed is a density sensing device of a fuel cell system and a fuel cell system having the density sensing device. The density sensing device includes a density sensor that includes a collision sensor and a variable resistor coupled to the collision sensor. The collision sensor is dipped into a fuel solution, and the collisions of molecules of the fuel solution are detected in the collision sensor. The resistance of the variable resistor varies depending on an amount of the collision detected by the collision sensor. The resistance further is converted to a density by the use of a table that includes a relationship between resistance and density. The density sensing device can further include a sensor driver. The sensor driver can be a piezoelectric member that is attached to the collision sensor. The collision sensor vibrates together with the piezoelectric member when a driving signal is applied to the piezoelectric member, which improves the accuracy of the measurement of the density.
摘要翻译： 公开了一种燃料电池系统的密度感测装置和具有该密度感测装置的燃料电池系统。 密度感测装置包括密度传感器，密度传感器包括碰撞传感器和耦合到碰撞传感器的可变电阻器。 将碰撞传感器浸入燃料溶液中，并在碰撞传感器中检测燃料溶液分子的碰撞。 可变电阻器的电阻根据碰撞传感器检测到的碰撞量而变化。 通过使用包括电阻和密度之间的关系的表格将电阻进一步转换为密度。 密度感测装置可以进一步包括传感器驱动器。 传感器驱动器可以是附接到碰撞传感器的压电构件。 当驱动信号施加到压电构件时，碰撞传感器与压电构件一起振动，这提高了密度测量的准确性。
