The Ministry of Industry and Information Technology (MIIT) has released a draft of the new national standard 'Safety Requirements for Fuel Cell Electric Vehicles' for public consultation. The draft introduces a hard constraint that the hydrogen emission rate for 70MPa high-pressure hydrogen storage systems must not exceed 8% to address safety risks in semi-enclosed spaces like tunnels. Additionally, the new standard mandates that vehicles equipped with 70MPa hydrogen storage tanks must be fitted with hydrogen refueling communication functions to prevent tank overheating during refueling and ensure the safety of high-pressure refueling operations.

What it means for you

• Obligations: Companies must ensure their fuel cell electric vehicles meet the new hydrogen emission rate limit and integrate mandatory hydrogen refueling communication functions for 70MPa tanks to pass the revised safety standard.
• Opportunities: Adhering to the updated standard will help companies gain market access and build consumer trust in the safety of their vehicles.
• Deadlines: Companies must prepare for the standard's potential adoption and implementation, as it is currently under public consultation.

What to do

ComplianceImmediately assess existing products for compliance with the new standard's requirements on hydrogen emission rate and hydrogen refueling communication functions, and develop a compliance plan.

EngineeringConduct hydrogen emission rate testing and develop hydrogen refueling communication functions for 70MPa high-pressure hydrogen storage systems to ensure product compliance with the new standard.

ProductCommunicate the impact of the new standard with industry associations and customers, and prepare relevant marketing materials to address market changes.
