The use of hydrogen containing impurities can cause damage to fuel cells after a short period of time. To counter this, guidelines for appropriate hydrogen purity have been established in International Standards ISO 14687:2019 and SAE J2719, which specify the maximum allowable impurity levels for compounds such as H2O, O2, He, N2, Ar, CO, CO2, TS, THC, HCHO, HCOOH, NH3, HBr, HCl und Cl2.
The V&F HydrogenSense is a combination of an electron impact (EI-MS) and a ion-molecule reaction (IMR-MS) mass spectrometer in one analyzer unit to measure all impurities in hydrogen for PEM fuel cells.
