J2579_200901: Technical Information Report for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles

Features

Issuing Committee: Fuel Cell Standards Committee

Scope

Content: The purpose of this document is to define design, construction, operational, and maintenance requirements for hydrogen fuel storage and handling systems in on-road vehicles.

Performance-based requirements for verification of design prototype and production hydrogen storage and handling systems are also defined in this document. Complementary test protocols (for use in type approval or self-certification) to qualify designs (and/or production) as meeting the specified performance requirements are described.

Crashworthiness of hydrogen storage and handling systems is beyond the scope of this document. SAE J2578 includes requirements relating to crashworthiness and vehicle integration for fuel cell vehicles. It defines recommended practices related to the integration of hydrogen storage and handling systems, fuel cell system, and electrical systems into the overall Fuel Cell Vehicle.

Rationale

Content

This Technical information Report (TIR) document provides initial information to be used in the design and construction of hydrogen storage and handling systems and is intended for use during the 2008-2009 pre-commercial period of technology development and vehicle evaluation. As a TIR, this document makes these safety criteria widely accessible for evaluation and preliminary use to confirm comprehensive utility with field experience in the 2008-2009 period.

Revision of this TIR is expected during the 2008-2009 period based on measurements, analyses and field experience with this design guidance and these test procedures. This first revision to the TIR addresses the following:

1)
The total allowable discharge from hydrogen storage systems (in Sections 5.1 and 5.2) were harmonized with the current version of SAE J2578. See Appendix D for further explanation.
2)
Minor changes to the Compressed Hydrogen Storage System qualification tests in Section 5.2 were made to clarify requirements.
3)
A localized leak requirement was added to Section 5.2 to minimize chance that localized fires that could occur would weaken materials and cause loss of gas containment.
4)
Appendix D was re-formatted to improve readability and understanding.
5)
Integration requirements for Compressed Hydrogen Systems (Appendix G) were harmonized with general guidance in Appendix E of SAE J2578.

This TIR should not be used as a requirement to qualify vehicles for on-road use until verification and validation is complete. This document is expected to be revised to become suitable as an SAE Recommended Practice or Standard in late 2009.
