FC4-H2-1000 Hydrogen Sensor Electrochemical High Sensitivity Micro Fuel Cells
Electrochemical Hydrogen Sensor
The FC4-H2-1000 long-life hydrogen sensor uses the principle of a micro fuel cell for detection. When hydrogen gas is present in the environment, gas molecules rapidly reach the sensor's core detection unit through natural diffusion and concentration polarization. Oxygen in the environment undergoes an oxidation reaction at the working electrode, while oxygen in the environment undergoes a reduction reaction at the sensor's counter electrode, forming a closed-loop reaction. The generated current is proportional to the hydrogen concentration in the environment. By measuring the magnitude of this current, the hydrogen content in the environment can be accurately quantified.
