Based on years of technical research and development and vehicle demonstration operation experience, SinoHytec independently developed hydrogen fuel cell engines using stack with its own intellectual property rights, which can operate when plugged in. At the same time, performance, reliability and maintainability are further improved, the operation doesn't need to be humidified and the cost is further reduced, which makes the products comparable to mainstream foreign products.

Core features

◆ Adopt stack with own intellectual property rights: low temperature start-up at -30℃, low temperature storage at -40℃;

◆ Highly integrated and modular design: saving space, easy maintenance and reduced maintenance cost;

◆ Remote intelligent monitoring and diagnosis technology: real-time monitoring of engine running status, real-time intelligent diagnosis of data.

The series products are made in China with independent intellectual property rights, and the localization rate of parts is as high as 100%. The highest mass power density exceeded 550W / kg, can self-start under a low ambient temperature of -30°C, and with a low-temperature storge at -40°C. It can be widely used in public transportation, logistics, intercity bus, heavy truck, sanitation vehicle, construction truck and other vehicles.

Technical highlights

Integration

EIS, DC / DC, low-voltage power distribution, high-voltage power distribution, air compressor controller, five parts in one PCU integration, Pack and DC integration, BOP cooling interface combination, wiring harness connection points reduced by 60%, more safe and reliable.

Generalization

The key BOP universal development of series engine products is convenient for maintenance.

Platformization

We managed to decrease the thickness of the bipolar plates used in our fuel cell stacks from 2.3mm to 1.6mm (a market leading results), and increased its power density while decreased the production costs by 50% in June, 2021.

Intellectualization

Self automatic tracking of environmental conditions, accurate control of stable stack output performance and the switching time is greatly shortened; self automatic tracking of altitude, adjusting stack working conditions, improving hydrogen utilization rate; self automatic diagnosis of engine parts’ functional status, ensuring reliable and stable operation and vehicle power demand; intelligent prediction of stack health status and online performance recovery; self adaptive adjustment of ejector operation can realize wide range decoupling control of hydrogen pressure and flow, respond to the needs of reactor water management, and improve environmental adaptability.
