Masterarbeit

Motivation:

Hydrogen technologies will continue to play a key role in achieving climate-neutral energy solutions. As there will no longer be a single universal solution, the integration of various technologies into hybrid systems becomes increasingly important. In this context, PEM fuel cells are typically operated in combination with batteries. However, the high dynamic load demands placed on fuel cells in such hybrid systems negatively affect their degradation behavior. The chosen operation strategy significantly influences both reversible and irreversible degradation, ultimately impacting the system’s total cost of ownership.

Task Description:

The objective of this thesis is to analyze the influence of key fuel cell stack parameters on both reversible and irreversible degradation mechanisms, with a particular focus on the membrane and electrode components. Each stack parameter shall be individually analyzed to assess its specific effect on the degradation behavior under various operational conditions.

In addition, suitable measurement and diagnostic methods shall be identified and examined with respect to their influence on degradation and their applicability for characterizing aging processes.

The results shall be structured and processed using Model-Based Systems Engineering (MBSE) approaches to enable a comprehensive and system-oriented understanding of degradation effects and their integration into higher-level system models and operational strategies.

Profile:

•             Independent and structured working approach

•             Strong interest in hydrogen technologies and renewable energy systems

•             Fluent in either German or English

•             Experience with Model-Based Systems Engineering (MBSE) is desirable
