Summary
The HERD Lab at the University of Wisconsin-Madison invites applications for a funded post-doctoral researcher position to study high temperature electrolysis cells and stacks for hydrogen and syngas production, and for electrochemical synthesis of high-value chemicals. The goal of the project is to experimentally characterize the electrochemical performance, investigate degradation phenomena, and mathematically simulate the operation of high temperature electrolysis cells to produce decarbonized molecules valuable for the heavy industry sector (steel, cement, chemicals and plastics industry). Single cells and stacks will be fabricated, assembled, and tested in our HERD Lab test cells and operated in atmospheric and pressurized conditions. Custom electrochemical and system models will be developed to support the experimental design and data analysis. The work will be carried out in close collaboration with national and international academic and industrial partners, part of a research consortium involved in the project.
More specifically, the work will focus on:
- Fabricating solid oxide cells and assemble them into short-stacks
- Scaling-up cell structures to achieve larger area cells and stack operation
- Testing and characterizing the electrochemical performance and durability of cells and stacks in the laboratory
- Developing models to reproduce the electrochemical performance of electrolysis cells and exploring the main degradation mechanisms
- Discovering novel thermodynamic and electrochemical cycles for efficient and cost-effective hydrogen/syngas production
The post-doctoral researcher will help build an interdisciplinary and dynamic team of researchers focusing on electrochemical energy conversion systems, hydrogen, electro-fuels, and industrial decarbonization. The candidate will supervise and mentor graduate students and help the PI manage the laboratory. The post-doctoral candidate will have the possibility of interacting with national and international research groups, national labs and private companies. While pursuing their independent research projects, the candidate will be expected to spearhead new research directions and collaborate with the PI to write new grant proposals. The candidate will also be expected to communicate research findings via peer-reviewed journal publications, presentations at national and international conferences, social media, and traditional news channels to increase the impact of their research.
Research Motivation
Both conventional solid oxide electrolysis (650-900°C) with oxygen anion (O2-) conducting dense ceramic membranes, e.g., yttria stabilized zirconia (YrZrO – YSZ), scandia stabilized zirconia (ScZrO – ScSZ), and newer proton conducting electrolysis cells (300-600°C) with proton conducting ceramic membranes (H+) are of interest for this project. Due to the endothermic nature of the electrolysis reactions, the thermal management of the cell and stacks is an important aspect to optimize their performance, understand their degradation mechanisms to extend lifetime, to ultimately reduce cost. The thermal balance between the endothermic reactions and the inevitable exothermic ohmic losses determines operational regimes that can be overall endothermic or exothermic in nature, depending on the value of current density. The ability to operate in endothermic conditions, allows these cells/stacks to be efficiently coupled to industrial processes characterized by waste heat rejection; relevant examples are steel furnaces, cement kilns, glass manufacturing, and chemical synthesis plants. When operated in endothermic conditions (i.e., below the thermoneutral voltage), we have demonstrated hydrogen production efficiencies <35 kWh/kg, compared to approximately 55 kWh/kg, typical of low temperature electrolysis technologies. The use of proton conducting ceramic devices is especially of interest for chemical synthesis applications, where hydrogenation and de-hydrogenation reactions can take place electrochemically. These mechanisms will be explored for the production of decarbonized molecules valuable for the plastic, fertilizer, and chemicals industries.
