Description Vendor

The Eltek Hydrogen Concentration Sensor operates as a catalytic combustion gas sensor within the hydrogen detectors product category. This device features high hydrogen selectivity to detect excessive hydrogen concentrations in the exhaust-gas channel of fuel-cell systems. It provides a quick response time of less than 100 ms and functions in high gas speeds of up to 50 m/s. The technology is intrinsically insensitive to humidity and offers two detection range versions, supporting up to 5 vol.% or up to 10 vol.% H₂.

Use Cases

  • Fuel-cell exhaust-gas monitoring
  • Detection of excessive hydrogen concentration after a fuel-cell fault
  • Monitoring mixed cathode and anode exhaust streams
  • Dynamic exhaust-gas measurement

Capabilities

  • Detects elevated hydrogen concentration in a fuel-cell exhaust channel
  • Measures hydrogen at concentrations up to the verified sensor range
  • Responds in dynamic gas-flow conditions
  • Operates without humidity-induced sensitivity
