HOW THE PRODUCT WORKS
Self-powered hydrogen measurement with a micro fuel cell
The FC-H2 Fuel Cell Hydrogen Sensor (model FC-H₂-1000) measures hydrogen concentration using a micro fuel-cell sensing principle. Hydrogen reaches the sensing element by natural diffusion. Oxidation at the positive electrode and oxygen reduction at the negative electrode create an electrochemical current proportional to hydrogen concentration, enabling quantitative measurement.
The sensor operates without an external power supply and is specified for a 0–1000 ppm measuring range, a 1 ppm lower detection limit and ±3% F.S. accuracy. It is intended for lithium-battery and energy-storage safety monitoring, residential and commercial water-gas alarms, industrial safety environments and fire-protection systems.
Mechanical dimensions
The cylindrical sensor body is specified at Ø13 ±0.2 mm, with a 6 mm body height and 11 mm overall height including pins. The pin spacings are 7.5 mm and 8.3 mm; pin width is 0.8 mm and pin thickness is 0.2 mm. The drawing also marks 12 ±0.3 mm, 6.8 ±0.3 mm, 5.4 mm and 1 mm mounting/lead dimensions. Confirm the dimension locations against the outline drawing before designing a PCB or enclosure. This dimensional check is useful when integrating a fuel cell hydrogen sensor into a battery safety alarm or hydrogen leak detection device.
