ISO 21087 is applicable to Proton exchange membrane (PEM) fuel cell applications for road vehicles.
ISO 21087 specifies the validation protocol of analytical methods used for ensuring the quality of the gaseous hydrogen (H2) at hydrogen distribution bases and hydrogen fuelling stations for road vehicles using proton exchange membrane (PEM) fuel cells. It also gives recommendations on the calculation of an uncertainty budget for the amount fraction.
Moreover, recommendations for keeping the integrity of the sample are also given in order to ensure the quality of the measurement. It also includes the requirements for reporting the analytical results.
Note-
The specific requirements for on-line monitoring are not covered by this document.
ISO 21087 on proton exchange membrane (PEM) fuel cell applications for road vehicles is useful for:
The hydrogen supply infrastructure for fuel cell electric vehicles (FCVs) requires specifications and an operational protocol for maintaining the quality of the hydrogen used to fuel the vehicles.
ISO 21087 is established mainly for analysis done after the sampling of hydrogen either at hydrogen distribution bases or at hydrogen refuelling stations.
ISO 21087 provides you with a list of suitable analytical techniques that will help you to measure each impurity in hydrogen, according to the specification of hydrogen grade D defined by ISO 14687 for permeating commercialized FCVs and hydrogen infrastructure in the market.
Overall, ISO 21087 sets criteria to validate the analytical methods that will help you for the quality control at hydrogen distribution facilities
