62818 2025 eng poster 0 -- -- -- Fuel cell electric vehicles are expanding quickly from light-duty to heavy-duty applications, such as buses or trucks. Hydrogen fuel quality needs to comply with ISO 14687:2025 to avoid any harmful impact on the vehicles. Total sulphur is one of the most impactful contaminants to a fuel cell system and has a threshold of 4 nmol/mol. In the European Partnership for Metrology (EPM) project Met4H2, BAM together with VSL, the National Metrology Institute of the Netherlands, developed novel gaseous primary reference materials (PRM) to improve the accuracy of the analysis of 7 sulphur compounds (hydrogen sulphide, carbonyl sulphide, methyl mercaptan, ethyl mercaptan, dimethyl sulphide, diethyl sulphide, and tetrahydrothiophene) for the quality control of hydrogen as fuel gas at this challenging amount fraction. These PRM were cross-validated using thermal desorption gas chromatography with a sulphur chemiluminescence detector (TD-GC/SCD). The results are presented and limits discussed.
