Abstract

Hydrogen used in proton exchange membrane-based fuel cell applications is subject to very high quality requirements. While the influences of contaminations in hydrogen on long-term stability have been intensively studied, the purity of hydrogen for mobile applications provided at hydrogen refueling stations (HRS) is rarely analyzed. Hence, in this study, we present sampling of hydrogen at HRS with a specially designed mobile tank for up to 70 MPa. These samples are precisely analyzed with a sophisticated ion molecule reaction mass spectrometer (IMR-MS), able to determine concentrations of contaminants down to the ppb-level. Sampling and analysis of hydrogen at an HRS supplied by electrolysis revealed a high purity, but likewise considerable contaminations above the threshold of the international standard ISO 14687:2019. In this study, a state-of-the-art analysis coupled with a developed methodology for fuel cell electric vehicle-independent sampling of hydrogen with a mobile tank system is demonstrated and applied for comprehensive studies of hydrogen purity.
