The hydrogen gas dispensed as fuel in refuelling stations for Fuel Cell Electric Vehicles (FCEV) should meet with purity requirements according to the actual normative. In this report we approach the preparation of hydrogen chloride/hydrogen (HCl/H2) standard gas mixtures, required to support the purity analysis of hydrogen fuel. The preparation of these mixtures was perform according to the gravimetric method, using dilution steps to reach the concentration level of 10 µmol/mol as the lowest. The mixtures were prepared in 5 L aluminium alloy cylinders with no internal treatment.
