About this position
This postdoctoral project is part of the H2-TWIN initiative and focuses on building the reference high-fidelity multiphysics model of a low-temperature PEM fuel cell system. The postdoctoral researcher will develop a physics-based model that serves as the starting point for later model reduction, so that a doctoral researcher can derive faster versions suitable for real-time simulation, control, monitoring, and sizing.
The work is centered on a PEMFC tested on the Toulouse Hydrogen Platform, where experimental data are available. The model will be developed in COMSOL Multiphysics and will couple the main physical and electrochemical phenomena involved in fuel-cell operation, including processes at the anode and cathode, proton and water transport through the membrane, gas transport in channels and diffusion layers, and thermal transfers.
The project is embedded in the LAPLACE research unit, a joint laboratory of the CNRS, Toulouse INP, and the University of Toulouse. LAPLACE is a major French center for electrical engineering and plasma research, and it has a long-standing activity in fuel-cell characterization and modelling. The postdoctoral researcher will compare the model against available experimental data such as polarization curves, electrochemical impedance spectroscopy, and cyclic voltammetry, and will assess the balance between accuracy and computational cost relative to existing tools used in the laboratory, including the pseudo-2D software Mephysto.
The expected outcome is a reusable benchmark model with accessible inputs, outputs, and parameters, designed for easy modification by future users and suitable for other operating conditions and configurations. Simulations will be driven by script-based interfaces between Python or MATLAB and COMSOL to generate frequency-domain and time-domain datasets. The model, its documentation, and tutorials will be released as an open benchmark, and the work is expected to produce scientific publications and conference presentations. The postdoctoral researcher will also help supervise a master’s intern working on the model and support the handover to the doctoral researcher responsible for reduction.
