Symbio is recruiting
Let's take a leap into the near future... Here we are at SYMBIO, one of the major up-and-coming players in zero-emission mobility
Our hyper-growth company designs Hydrogen Systems that can be integrated into several types of electric vehicles (vans, buses, trucks, boats).
Founded in 2010, Symbio is an equally-owned subsidiary of the Michelin and Faurecia groups. Our company's ambition is to grow in a competitive environment thanks to its employees. Indeed, management in our company is based on trust, openness and commitment
We aim to develop multi-scale models to describe and understand degradation mechanisms under steady-state and transient operations. The main objective is to analyse the interaction between degradation mechanisms and the impact on fuel cell performance. Moreover, materials properties impacts on theses mechanisms need to be studied in order to optimize cell components and design. Calibration and validation of degradation models will be performed using standard electrochemical characterization and post-mortem analyses.
Main steps:
- Bibliographic study.
- Development of a cell performance model including main degradation mechanisms in COMSOL:
- Pt dissolution
- Carbone corrosion
- Membrane chemical and mechanical degradation
- GDL degradation
- Validation of the model using standard electrochemical characterization and post-mortem analyses.
- Quantification of the impact of each degradation mechanisms under typical conditions in Symbio stack.
- Proposing guidelines for future MEA developpements
All our offers are open to people with disabilities (RQTH)
