International technical committees have been created inside the ISO and IEC organisations so as to facilitate the world-wide industrialisation and commercialisation of hydrogen systems and fuel cells. The working group ISO TC 197 entitled Hydrogen Technologies has already published international standards and is very active in the edition of standards for all the hydrogen chain from production to end use. The working group IEC TC 105 focuses on fuel cell technologies. It is also currently drafting many standards for fuel cell applications (mobile, stationary, portable and micro fuel cells). At an international level, the UNECE is actively working for the publication of two Global Technical Regulations for vehicles fuelled with gaseous or liquid hydrogen. And, finally, many European projects intend to facilitate the implementation of a harmonised and well-adapted regulation and standardisation framework.
