Standard for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles
<p>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.</p> <p>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.</p> <p>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.</p> <p>NOTE: Ultimate design qualification for crash impact resistance is achieved by demonstrated compliance of the vehicle with applicable regulations.</p>
Rationale: There are several key aspects of Compressed Hydrogen Storage Systems (CHSSs) on hydrogen and fuel cell vehicles that are currently being studied and targeted for revision -- hydrogen material compatibility and fire testing. Opening the document at this time will allow the Safety Task Force to capture proposed revisions and allow review by the entire team.
