Product Description:
YJJ MEv-GH01 Electrochemical Fuel Cell Type Hydrogen H2 Sensor for Hydrogen Leakage Detection
Features:
I. Core Parameters (Official Standards) Table
Project Specification Explanation
Gas to be detected Hydrogen (H₂) Flammable and explosive gas. Explosion limit: 4.0% ~ 75.6%
Detection principle Electrochemical (fuel cell type) H₂ oxidizes at the electrode to generate current. Current ∝ concentration (Faraday's Law)
Measurement range 0 ~ 2000 ppm Standard safety monitoring range (100% LEL ≈ 40000 ppm)
Overload capacity 5000 ppm Does not damage in short-term overload
Sensitivity 0.5 ~ 1.5 nA/ppm Typical micro-ampere level current output
Resolution 1 ppm Minimum concentration change detectable
Response time (T90) < 30 seconds Response speed to 90% concentration
Load resistance 500Ω / 1kΩ / 2kΩ Recommended external resistance value
Operating temperature -10℃ ~ +50℃ General industrial / vehicle environment
Operating humidity 15 ~ 90% RH (no condensation) Adaptable to most indoor and outdoor scenarios
Service life Up to 10 years Long service life, maintenance-free
Size Micro metal package (φ approximately 12mm) Suitable for portable / embedded devices
II. Main Applications (Applicable Scenarios)
Core positioning: Low concentration H₂ leakage safety monitoring (civilian / commercial / vehicle / energy storage)
New energy vehicles (hydrogen fuel cell vehicles)
Leakage alarm for hydrogen storage tanks, pipelines, fuel cell systems
Real-time monitoring of hydrogen concentration in vehicles
Safety of energy storage stations / battery boxes
Li-ion energy storage cabinets / containers: Trace H₂ detection during overcharging, thermal runaway
Early fire / leakage warning in energy storage systems
Industrial / commercial safety
Chemical, semiconductor, electronics factories: H₂ leakage monitoring
Safety inspection and alarm in laboratories, gas cylinders, pipelines
