Main Research Activities
This PhD thesis is a collaborative project between LRCS in Amiens and the Lyon-based fuel cell company, Symbio. The goal is to describe and understand the degradation mechanisms occurring in Symbio cells, in both steady-state and transient regimes. The degradation models found in the literature are not necessarily all relevant for application to industrial fuel cells. Therefore, a methodology based on observations of current systems at Symbio will be established to develop a relevant multiphysics degradation model that can guide future developments. Depending on the observations, the approach for developing the model can be decided. Model development might involve a local-scale study to thoroughly understand the impact of operating conditions and material parameters on the modelled degradation phenomena or directly develop a cell-scale degradation model that highlights the spatial distribution of degradation in cells. The calibration of the physics and validation of the degradation model will be carried out using standard electrochemical characterizations and post-mortem analyses.Academic Training
