Course paper / final thesis

1D+1D modeling of reversible Solid Oxide Cell (rSOC) reactors for steady state and dynamic process analyses of electricity storage systems

Starting date


Duration of contract

6 months

Type of employment

Full-time (part-time possible)

Your mission:

The intermittent nature of renewable energy sources demands energy storage systems to stabilize the grid. These energy storage systems are required to be versatile and offer a wide range of power and energy density. The Institute of Engineering Thermodynamics at DLR is working on novel solutions based on rSOC reactors. In this concept, excess electricity from renewable sources is stored by converting water to produce storable hydrogen. In reverse mode the hydrogen can be used to produce power within the same rSOC reactor when demand exceeds supply.

Within the scope of the master thesis a 1D+1D model of an rSOC electrochemical reactor should be developed and implemented with Dymola(Modelica) software. An experimentally validated 1-D model of an rSOC single repeat unit (SRU) is available in house and would be used as a basis for further improvement. The single cell model should be refined and expanded into 1D+1D multi cell rSOC stack model. The rSOC stack model will be validated against the experimental results available within the department. The final 1D+1D rSOC stack model must be modular, computationally efficient and compatible for process system modeling. The final results will be published in a reputed peer-reviewed journal.

Your qualifications:

  • self-motivated student with a strong interest in exploring novelty is highly encouraged
  • background in chemical or process systems engineering, electrochemistry, numerical computation is required
  • programming experience or knowledge preferably with Modelica language is required, proficiency or knowledge of other scientific programming languages is also accepted
  • previous knowledge of Solid Oxide Electrolysis Cell and Solid Oxide Fuel Cell is advantageous
  • fluency in written and spoken English is required

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Reconciling family and working life as well as equal opportunities for women and men are an integral part of our HR policy. We therefore strongly encourage applications from women.
