PEMFC Parameter Identification
The core challenge addressed is the precise identification of unknown parameters for Proton Exchange Membrane Fuel Cells (PEMFCs). Accurate parameter estimation is crucial for developing reliable mathematical models that reflect the actual behavior of PEMFC systems under various operating scenarios. The GPC algorithm utilizes the Sum of Squared Errors (SSE) between estimated and experimental voltage data as its fitness function, aiming to minimize this error for optimal parameter values. This is vital for R&D in sustainable energy, enabling predictive maintenance and efficient system design for fuel cell technologies.
Hybrid Swarm Intelligence (GPC)
The Grey Particle Cuckoo (GPC) algorithm combines the strengths of Grey Wolf Optimizer (GWO), Particle Swarm Optimization (PSO), and Cuckoo Search (CS). This hybrid approach features a layered hybridization model that balances exploration and exploitation. Early stages use Lévy flights (from CS) for wide exploration, while later stages incorporate GWO's hierarchical decision-making and PSO's adaptive velocity updates to intensify convergence. This structured orchestration mitigates the limitations of individual algorithms, enhancing search efficiency and robustness in complex, high-dimensional optimization problems.
Rigorous Performance Validation
The GPC algorithm's efficacy is rigorously validated through several statistical analyses. It was tested on 100-digit CEC 2019 benchmarks, outperforming other metaheuristic algorithms in 6 out of 10 challenges. Non-parametric tests, including Friedman and Wilcoxon signed rank tests, consistently demonstrated GPC's superiority in terms of solution quality and convergence speed. Metrics such as Mean Square Error (MSE), Individual Absolute Error (IAE), Mean Bias Error (MBE), Mean Absolute Error (MAE), and Root-Mean-Square Error (RMSE) further confirmed its optimal performance compared to 11 other algorithms.

Case Study: NedStack PS6 PEMFC Parameter Extraction
The GPC algorithm was applied to a commercial NedStack PS6 PEMFC stack (6kW rated power, 65 cells). It achieved the lowest SSE value of 2.26768E+00, significantly outperforming 11 other metaheuristic algorithms (ZOA, SCHO, PSA, SABO, YDSE, EDO, RIME, CDO, COA, HHO, GWO).
The model curves (I-V and I-P) generated by GPC's extracted parameters showed excellent alignment with experimental data, with minimal variation. This precise parameter identification ensures high fidelity in modeling the PEMFC's behavior, crucial for optimizing performance under various temperature and pressure conditions (e.g., PH2/PO2 changes from 1.000/1.000 to 4.000/2.500 bar and temperatures from 303K to 353K). The algorithm's consistent first-rank in Friedman and Wilcoxon statistical tests for this real-world application underscores its reliability and accuracy in enterprise energy system development.
