Predictive virtual modelling framework for performance and platinum degradation modelling of high temperature PEM fuel cells
9
TL;DR: An innovative modelling framework is presented based on a mechanistically based spatially and temporally resolved HT-PEMFC performance model and modular degradation modelling framework based on interacting partial platinum degradation mechanisms for more efficient and systematic model supported design of FCs and in-depth understanding of cause and effect chain from FC operation to its degradation.

Theoretical analysis of particle size re-distribution due to Ostwald ripening in the fuel cell catalyst layer
Ambrož Kregar,Tomaž Katrašnik +1 more
TL;DR: In this paper, the authors systematically studied how the modeling approach towards the electrochemically driven Ostwald ripening in the fuel cell catalyst differs from the classical diffusion driven models and highlighted how these differences affect the resulting evolution of particle size distribution.

Identifiability Analysis of Degradation Model Parameters from Transient CO2 Release in Low-Temperature PEM Fuel Cell under Various AST Protocols
TL;DR: In this article, a mechanistically based PEMFC modeling framework, comprising real-time capable fuel cell performance, and platinum and carbon support degradation models, is proposed to model transient CO2 release rates in the LT-PEMFCs with the consistent calibration of reaction rate parameters under multiple different accelerated stress tests at once.
