FC-H2S-100 Hydrogen Sulfide Gas Sensor Micro Fuel Cells

The FC-H2S-100 hydrogen sulfide sensor utilizes the principle of a micro fuel cell for detection. When hydrogen sulfide is present in the environment, gas molecules rapidly reach the sensor's core detection unit through natural diffusion and concentration polarization. An oxidation reaction occurs at the positive electrode, while oxygen in the environment undergoes a reduction reaction at the sensor's negative electrode, forming a closed-loop reaction. The generated current is proportional to the hydrogen sulfide concentration in the environment. By measuring the magnitude of this generated current, the hydrogen sulfide gas content in the environment can be accurately quantified. This sensor is an electrical-free device, requiring no external excitation for the reaction process. It offers outstanding advantages such as zero power consumption, low noise, high detection accuracy, and a long service life.
