AI Technical Summary

Technical Problem

In the existing technology, the coupling control of hydrogen circulation and cooling system of fuel cells lacks predictability, making it difficult to quickly coordinate the actions of multiple actuators when the load changes abruptly, resulting in temperature overshoot or oscillation, and making it difficult to adapt to the instantaneous heat surge caused by sudden load changes in fuel cells.

Method used

An integrated hydrogen cycle cooling system for fuel cells is constructed, comprising a multi-source state perception module, a Markov decision process modeling module, a reinforcement learning decision module, and an execution control module. By collecting multi-dimensional state data in real time, a Markov decision process model is constructed to generate a collaborative control strategy for the hydrogen cycle-cooling system. Temperature fluctuations are rapidly suppressed through the joint regulation of the hydrogen cycle and cooling system.

Benefits of technology

Significantly improves the accuracy and stability of temperature control, reduces temperature overshoot, ensures the fuel cell stack operates within the optimal temperature range, extends service life and improves energy conversion efficiency, while also optimizing the energy consumption of the hydrogen circulation pump and cooling system, thereby improving overall energy efficiency.
