Analysis of GB/T 26990-2023,Fuel cell electric vehicles—Onboard hydrogen system technical specifications
摘要
Abstract
In recent years,with the continuous technological upgrading of fuel cell electric vehicles,compared with 35 MPa onboard hydrogen system,the onboard hydrogen system with a nominal pressure of 70 MPa has the advantage of high volume density of hydrogen storage,which can improve the driving range of vehicles,and is widely used in passenger vehicles.However,GB/T 26990-2011,Fuel cell electric vehicles—Onboard hydrogen system—Specifications,and GB/T 29126-2012,Fuel cell electric vehicles—Onboard hydrogen system—Test methods,are only suitable for onboard hydrogen systems with a nominal working pressure of no more than 35 MPa,and these versions of the standards were implemented for more than ten years,which can no longer fully adapt to the current technical status of onboard hydrogen systems of fuel cell electric vehicles.Therefore,in November 2023,China issued GB/T 26990-2023,Fuel cell electric vehicles—Onboard hydrogen system technical specifications,which revises and adds some technical contents to adapt to the current development of the fuel cell electric vehicle industry.This paper elaborates on the main technical content of GB/T 26990-2023 and the similarities and differences with the previous version of the standard,and interprets relevant technical contents and testing methods in the new standard for the reference of enterprises in the industry.关键词
