Six-in-one Integration

It incorporates an advanced boost DC-DC converter, an air compressor controller, a high-voltage distribution unit, and electrochemical impedance spectroscopy technology for precise system diagnostics. Additionally, it features a step-down DC-DC converter and an integrated insulation tester to ensure safety and reliability. The design simplifies the wiring harness and structural layout, reducing complexity and potential failure points. Furthermore, it significantly enhances electromagnetic compatibility (EMC) and mitigates electromagnetic interference (EMI), ensuring stable operation even in demanding environments.

High Insulation Level

By modifying the coolant circuit to float its auxiliary components and integrating the deionized water exchange column in a parallel configuration with the inlet and outlet of the stack cooling system, the electrical insulation resistance of the engine in its operational (hot) state is significantly enhanced. This optimization increases the insulation value to over 6MΩ, ensuring improved electrical isolation and system reliability during high-temperature operation.

Intelligent Water Management

Using electrochemical impedance spectroscopy (EIS) detection combined with advanced intelligent algorithms, precise water management is achieved for both the cathode and anode in fuel cell stacks. This method continuously monitors and analyzes key electrochemical parameters to optimize water distribution, ensuring stable operation. Maintaining ideal hydration effectively minimizes the risk of critical failures such as cathode flooding, which can obstruct gas flow and reduce performance, and membrane drying, which leads to decreased ionic conductivity and potential damage. This approach significantly enhances the reliability, efficiency, and longevity of the fuel cell system.

Quick Cold Start

By applying the thermodynamic principle of compressed gas, the module can be quickly started at low temperatures using an air compressor heating solution.

Anti-decay Shutdown

The cathode inlet and outlet feature a double throttle design, which effectively slows down performance degradation of the fuel cell stack through oxygen consumption shutdown and a cathode hydrogen reduction strategy.

Efficient Energy Recovery

The implementation of turbine expansion technology significantly reduces the loss of module accessories, achieving an impressive loss ratio of 13%. This advancement not only improves efficiency but also ensures more effective resource utilization, resulting in enhanced overall performance.

Multi-stage Hydrogen Cycle Injection

The system adopts advanced multi-stage hydrogen cycle injection technology, designed to optimize hydrogen utilization across various operating conditions. By incorporating a graded injection approach and a self-learning control algorithm, the control strategy intelligently adjusts hydrogen injection rates in real-time. This ensures precise delivery of hydrogen under all operating scenarios, achieving comprehensive coverage for diverse performance requirements. Additionally, this innovative approach significantly reduces anode-side auxiliary hydrogen consumption, enhancing overall efficiency and minimizing waste.
