Researchers have developed a novel hard-constraint physics-residual network (PR-Net) for predicting hydrogen crossover in polymer electrolyte membrane water electrolysis (PEMWE). This PR-Net integrates fundamental physics laws as a deterministic backbone, learning only a residual correction for unmodeled nonlinear effects. It significantly outperforms traditional data-driven neural networks and soft-constraint physics-informed neural networks in both prediction accuracy and extrapolation capabilities, particularly at high pressures.
