ECoProbe- Visualizing Energy Conversion Pathways
The section for Imaging and Structural Analysis (ISA) in the Department of Energy Conversion and Storage at the Technical University of Denmark is seeking a candidate for a PhD position as part of a Danish Research Council project on in-operando scanning probe microscopy on electrochemical cells for energy applications.
DTU Energy Conversion is among the world’s leaders in the research and development of solid oxide fuel cells (SOFCs), electrolysis cells (SOECs) and other energy conversion technologies. DTU Energy Conversion has cutting edge facilities and competences for fabrication, testing and characterisation of energy conversion technologies.
The PhD project will be conducted in close collaboration with the Center for Nanophase Materials Science at Oak Ridge National Laboratory (USA) who is at the forefront of development of advanced in-operando SPM techniques.
Solid oxide fuel/electrolysis cells (SOFC/SOEC) will play an important role in future efficient and environmentally friendly energy systems if a better long term performance of the cells can be achieved. Impressive performance improvements have recently been reported for cells with specific multiphase nano-structures, but structural and compositional nano-scaled changes can lead to deactivation. The dynamics of the critical structures are not understood, and further studies are hampered since there are no available methods which offer in situ characterization of operating cells with nano-scale spatial resolution.
The aim of ECoProbe is to create the basis for in-operando localized probing of solid oxide fuel cells (SOFCs) and electrolysis cells (SOECs) with unprecedented spatial resolution by extending the limits of our novel unique instrumentation for controlled atmosphere high temperature scanning probe microscopy (CAHT-SPM) and combining it with ambient pressure X-ray photoelectron spectroscopy (AP-XPS) for the first time.
This synergistic methodological approach will provide 1) direct probing of the local electric potential distribution and 2) mapping of the microstructure and surface chemical composition in operating solid oxide cells (SOCs). ECoProbe will thus unravel the complex electrode processes and degradation mechanisms observed in today’s SOCs.
As a PhD student at DTU Energy Conversion you will be part of the ISA team, but also interacting regularly with other researchers within the Department and researchers at Oak Ridge National Laboratory.
The PhD position has a multidisciplinary nature and thus you will need to draw on the knowledge of several experts to reach the project aims. You will be primarily engaged with carrying out in-operando CAHT-SPM on real SOEC and SOFC under varying operating conditions so as to visualize different activation/deactivation and degradation mechanisms in action at selected locations in the cell and to measure the time evolution of the electric potential distribution within the electrode, which is anticipated to lie at the heart of the different degradation patterns.
A multiplicity of advanced scanning modes will be employed to establish the link between local chemical, microstructural, and corresponding electrochemical phenomena responsible for the observed activation/deactivation and degradation phenomena.
We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the PhD guide.
Salary and appointment terms
Salary and appointment terms are consistent with the current rules for PhD degree students in Denmark.
The period of employment is 3 years and the place of work is at DTU Energy Conversion on Risø Campus.
The start date is 1 January 2015 but can be negotiated within a small time margin.
