氢气传感器在氢气泄漏检测中有着广泛的应用。这些传感器也可用于过程监控。我们实验室研制了一种基于燃料电池的室温电流型氢传感器。该传感器用于研究EAC配方（EDTA、抗坏血酸和柠檬酸的混合物）对碳钢（CS）的腐蚀。EAC配方是推荐的化学配方，用于溶解CS腐蚀形成的磁铁矿。本文介绍了一种新的方法，使用氢传感器获得的腐蚀速率的CS EAC作为时间的函数。
Hydrogen sensors find extensive application in hydrogen leak detection. These sensors can also be utilized in process monitoring. A fuel cell based room temperature amperometric hydrogen sensor has been developed in our laboratory. This sensor is used to study corrosion of carbon steel (CS) with EAC formulation, which is a mixture of EDTA, ascorbic acid and citric acid. EAC formulation is a recommended chemical formulation to dissolve magnetite formed by corrosion of CS. The paper describes a new method using hydrogen sensor to obtain the rate of corrosion of CS by EAC as a function of time.
