Fuel specification for proton exchange membrane fuel cell vehicles - Hydrogen 1 Scope This standard specifies the terms and definitions, hydrogen purity, requirements of impurity content in hydrogen and the analytical test methods for hydrogen fuel used for proton exchange membrane fuel cell (PEMFC) vehicles. It is applicable to the quality requirements of hydrogen fuel used for PFSA proton exchange membrane fuel cell vehicles. Note: Molecular formula of hydrogen: H2. The relative molecular mass is 2.01588 (as per 2007 international relative atomic mass). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
