Abstract
Low temperature proton exchange membrane fuel cells (LT-PEMFCs) represent a promising solution for sustainable aviation, but their design for aircraft applications is
hindered the high computational cost of high-fidelity modelling. This study introduces a multi-fidelity optimisation framework that combines multiple LT-PEMFC models at different levels of fidelity within a Non-Myopic Multi-Fidelity Bayesian Optimisation active learning scheme. By formulating the design search as a dynamic decision process, this scheme efficiently allocates computational resources across fidelities, enabling accurate yet tractable exploration of the design space. The proposed multi-fidelity framework identifies high-power
and physically consistent LT-PEMFC configurations at a fraction of the cost of traditional single-fidelity optimisation, providing a scalable pathway for zero-emission aircraft design.
