Chinese automaker Dongfeng Motor announced that its independently developed 400kW hydrogen fuel cell platform became the first domestically produced metal bipolar plate fuel cell stack to pass the country’s new national standard 10,000-hour durability verification.

The announcement came during the “Hydrogen Powering Dongfeng, Leading the Future” conference held in Wuhan on May 20.

Alongside the durability milestone, the automaker also unveiled its T1 commercial vehicle new energy platform aimed at accelerating the large-scale adoption of hydrogen-powered commercial vehicles.

The company said the new platform focuses on delivering a “fast, efficient, and cost-effective” operating experience for commercial transport users while supporting China’s broader push toward carbon reduction and new energy technologies.

The durability test

According to the company, the durability verification simulated real-world heavy commercial vehicle operating conditions, including frequent start-stop cycles and severe load fluctuations.

The testing assessed material stability, structural reliability, and long-term performance degradation of the hydrogen fuel cell stack.

The company stated that the testing process received recognition from third-party testing institutions and industry experts, validating the durability and stability of the 400kW platform.

Durability remains one of the biggest barriers to large-scale commercialization of hydrogen fuel cell technology, particularly in long-haul freight transport where vehicles operate continuously under demanding conditions.

To address this, Dongfeng said it developed what it calls a “2-3-3” durability technology system, enabling breakthroughs across multiple stages of fuel cell development, from materials to system integration.

The company has now built three hydrogen fuel cell power platforms — 70kW, 150kW, and 400kW — covering commercial applications ranging from 20kW to 400kW.

Among them, the 400kW platform was designed specifically for 49-ton heavy trucks. It supports cold starts at temperatures as low as -40°C (104°F) and has a design lifespan exceeding 30,000 hours.

Targeting long-haul transport

Leveraging its hydrogen energy technology system, Dongfeng also introduced its T1 commercial vehicle new energy platform.

The platform focuses on four major areas: low energy consumption, lightweight construction, rapid refueling, and high safety standards.

According to the company, hydrogen-powered vehicles built on the platform achieved hydrogen consumption as low as 7 kilograms per 100 kilometers during testing across mountainous and plain regions.

Dongfeng Motor also stated that its 49-ton hydrogen-powered tractor unit weighs only 8.8 tons while delivering a driving range of up to 1,700 kilometers with just 15 minutes of refueling.

Hydrogen commercial vehicles gaining momentum

Hydrogen-powered commercial transport has increasingly emerged as a major focus area in China’s new energy strategy, especially for heavy-duty logistics where battery-electric solutions can face payload and charging limitations.

Dongfeng stated that its hydrogen-powered heavy trucks and passenger vehicles have already accumulated more than 1 million kilometers of real-world operating mileage across multiple commercial scenarios.

To support deployment, the company has also built an integrated service network that includes more than 700 service stations, over 200 dedicated experts, more than 100 parts centers, and a dynamic parts reserve valued at 180 million yuan.

The company said the network is designed to provide full lifecycle support for hydrogen vehicle users as commercial adoption continues to expand.
