Hard-constraint physics-residual networks for hydrogen crossover prediction and high-pressure extrapolation in PEM water electrolysis
A PINN trained on augmented hydrogen-crossover measurements is claimed to predict PEM electrolyzer crossover accurately, but the abstract's hard-constraint PR-Net results (R2=99.6%, extrapolation R2=94%) are not reproduced in the body, which reports a soft-constraint PINN with fusion extrapolation (
