Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 34537-2017
1. Background and Significance of the Standard
GB/T 34537-2017 "Compressed Hydrogen and Natural Gas Mixed Fuel for Vehicles" is an important standard for the application of hydrogen energy in the field of vehicle fuel. The standard was proposed and managed by the National Hydrogen Energy Standardization Technical Committee, and aims to standardize the technical requirements, test methods, transportation, storage and use of compressed hydrogen and natural gas mixed fuel for vehicles.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 34537—2017 | GB 18047 (Compressed natural gas for vehicles) | ISO 12619 (Compressed hydrogen for road vehicles) |
|---|---|---|---|
| Scope of application | Compressed hydrogen and natural gas mixed fuel for vehicles, pressure ≤35 MPa, hydrogen content ≤25% | Compressed natural gas for vehicles | Components of compressed hydrogen systems for road vehicles |
| Technical indicators | Hydrogen purity (volume fraction): 2≤p(H)≤25% | Natural gas quality requirements | Hydrogen system safety specifications |
| Test methods | GB/T 11062, GB/T 3634.1, etc. | GB/T 11062 | ISO specified methods |
3. Implementation suggestions
Hydrogen content monitoring:It is recommended to use a gas chromatograph to regularly detect the hydrogen content in the mixed gas to ensure that it meets the standard requirements (≤25%).
Storage container selection:For pressure ≥20 MPa or hydrogen content ≥20%, Type III bottles should be used first to ensure safety.
