Description

Hydrogen that contains impurities can damage fuel cells within a short time. The international standards ISO 14687:2019 and SAE J2719 therefore define hydrogen purity requirements and set maximum permissible levels for impurities such as H2O, O2, He, N2, Ar, CO, CO2, total sulfur, total hydrocarbons, HCHO, HCOOH, NH3, HBr, HCl and Cl2.

The V&F HydrogenSense combines an electron impact (EI-MS) and an ion-molecule reaction (IMR-MS) mass spectrometer in one analyzer unit to measure all impurities in hydrogen for PEM fuel cells.

Typical applications

  • Purity testing of hydrogen for PEM fuel cells

Measurable compounds

  • Permanent gases: H2, O2, N2, CO, CO2
  • Moisture: H2O
  • Noble gases: He, Ar
  • Hydrocarbons: CH4, C6H6, C7H8
  • Sulfur compounds: H2S, COS, CS2, R-SH (mercaptans)
  • Other: CH2O (formaldehyde), CH2O2 (formic acid), NH3
  • Halogenated compounds: HBr, HCl, Cl2, R-X (organic halides)

Values marked as application-dependent (measuring range, response time, detection limit, gas consumption) depend on the compounds measured, the system configuration and the instrument settings.
