The FC-H2-20000 Long-Life Hydrogen Sensor utilizes micro fuel cell technology for hydrogen detection. It operates by oxidizing hydrogen at the anode and reducing oxygen at the cathode, forming a closed-loop reaction. The generated current is directly proportional to the hydrogen concentration, allowing for precise quantification. This passive sensor boasts zero power consumption, low noise, high detection accuracy, a long service life, and excellent resistance to interference and poisoning across a wide temperature range.
