Description / Abstract:
This Standard provides background information and a hydrogen
fuel quality standard for commercial proton exchange membrane (PEM)
fuel cell vehicles. This Report also provides background
information on how this standard was developed by the Hydrogen
Quality Task Force (HQTF) of the Interface Working Group (IWG) of
the SAE Fuel Cell Standards Committee.
Purpose
The purpose of this hydrogen fuel quality standard is to specify
hydrogen fuel quality requirements for all commercial hydrogen
fueling stations for PEM fuel cell vehicles (FCVs) Hydrogen quality
is defined as the quality measured at the dispenser nozzle using a
suitable adapter and methodology developed by the ASTM D03 (Gaseous
Fuels) Committee.
Field of Applicability
This hydrogen quality standard is applicable to PEM FCVs at the
point of interface between the fueling station and the vehicle. The
specification of hydrogen quality is intended to meet the
requirements of FCVs, and will meet or exceed the requirements of
ICEVs to the extent that they have been determined. Information
considered in the specification of the fuel quality includes:
Applicable standard chemical analysis methods to quantify the
presence of identified H2 impurities
Infrastructure sources of contaminants and cost related to
production, distribution, storage and handling of H2
Fuel cell systems, specifically, levels of contaminants that
adversely impact performance and/or durability
On-board hydrogen storage and delivery systems
Relationship of SAE Standard to ISO and ASTM Standards
The content of this standard was coordinated with ISO TC197/WG12
(H2 Fuel – Product Specification Working Group) as well as the ASTM
D03 (Gaseous Fuels) Committee and is consistent with ISO 14687
Part2.
