摘 要：The goal of this Task Order was to assess the proposed test conditions used for evaluating life cycle durability of high-pressure hydrogen fuel containers. The key test conditions evaluated were representative high and low cycling temperatures, static hold time at high pressure, and the number of pneumatic hydrogen cycles required to reveal poor durability performance of high-pressure hydrogen fuel containers. The results of this Task Order provide data for NHTSAs assessment and consideration as it evaluates the safety performance of compressed hydrogen fuel systems and the need for enhancement of appropriate FMVSS. In addition, the results of this Task Order provide data to assist in resolving several open issues and concerns in the pneumatic test sequence of the 2009 edition of the Expected-Service Performance Verification Test procedure in the SAE Technical Information Report (TIR) 2579 for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles.
