Ankai HFF6121G03FCEV bus (fuel cell 24-46 seats)

Ankai HFF6121G03FCEV Bus (24-46 Seats Fuel Cell)

The Ankai HFF6121G03FCEV, a green pioneer in hydrogen-powered buses, is a 2025 model. The HFF6121G03FCEV is a city bus developed by Ankai Bus based on fourth-generation hydrogen fuel cell technology, offering flexible configurations of 24 to 46 seats. Featuring a low-floor, fully load-bearing structure, it is equipped with a 120kW hydrogen fuel cell system and 70MPa high-pressure hydrogen storage technology. This enables a -30°C cold start and 15-minute rapid hydrogen refueling, with a CLTC range exceeding 500 kilometers, providing a zero-emission solution for urban public transportation.

Technical Highlights

The hydrogen-electric hybrid platform integrates a 120kW proton exchange membrane fuel cell and a lithium iron phosphate power battery. Its dual-energy synergistic control strategy increases energy efficiency to 92%. Equipped with an axial flux permanent magnet motor (peak power of 360kW), it accelerates from 0 to 50 km/h in just 9.8 seconds, adapting to frequent start-stop cycles.

The intelligent safety system features three-level hydrogen leak detection (ppm-level accuracy) linked to the EBS electronic braking system, shutting off the hydrogen supply in 0.1 seconds in emergencies. The vehicle has passed EU ECE R66 rollover certification and features a 7-series aluminum alloy anti-collision beam design.

Scenario-Based Energy Management

Supports V2G vehicle-to-grid interaction technology, enabling reverse power supply during off-peak hours (maximum daily output of 120 kWh). A photovoltaic roof system provides auxiliary power for onboard equipment, generating an average of 10 kWh per day.

Vehicle Configuration

The Urban Trunk Edition (24-32 seats) features a low-floor design (step-through height ≤ 350 mm), a wheelchair securement area, and a dedicated seat for mothers and infants. Optional features include a driver fatigue monitoring system and a water-fording warning system (maximum wading depth 400 mm), making it suitable for operation in rainy areas.

The Express Commuter Edition (33-46 seats) features an optimized standing area and a passenger capacity of up to 90. An integrated intelligent vehicle speed coordination system enables coordinated vehicle-road operation within BRT lanes, improving peak-hour transportation efficiency by 40%.

Designed for locations above 3,000 meters in altitude, the turbocharged air supply system automatically compensates for 15% of power output, and a diffuse oxygen supply module is added to the cabin to ensure power stability and passenger comfort in high-altitude operating conditions. The three-electric system comes with an extended warranty of 8 years/500,000 kilometers, and the hydrogen fuel cell stack has a lifespan exceeding 30,000 hours, setting a benchmark for the durability of hydrogen-powered buses.
