Supervisor: Dr. Luca Mastropasqua
The HERD Lab at the University of Wisconsin-Madison invites applications for a funded graduate student position to investigate proton conducting ceramic electrochemical cells for water splitting (i.e., hydrogen production) and hydrogen separation. This project involves the study of proton conducting ceramic electrolyzers and electrochemical membranes for hydrogen separation operating at temperature <600°C. The project will be primarily experimental in nature, with the goal of manufacturing and testing the electrochemical performance of single cells and stacks. 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:
- Developing novel electrode-supported ceramic structures to achieve mechanically resistant and high surface area assemblies
- Scaling-up cell structures to achieve larger area cells and stack operation
- Testing and characterizing the performance of cells and stacks in the laboratory
- Developing models to reproduce the electrochemical performance of proton conducting cells
- Discovering novel thermodynamic and electrochemical cycles for efficient and cost-effective hydrogen production and separation
The student will help build an interdisciplinary and dynamic team of researchers focusing on electrochemical energy conversion systems, hydrogen and electro-fuels, and industrial decarbonization. The student 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 gain exposure to professional networking events and invaluable grant writing experience. 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.
Conventional high temperature electrolysis (650-900°C) uses oxygen anion (O2-) conducting dense ceramic membranes, e.g., yttria stabilized zirconia (YrZrO – YSZ), scandia stabilized zirconia (ScZrO – ScSZ), or Lanthanum strontium gallium magnesium oxides (LSGM). Contrary to oxygen conducting ceramics, protonic conducting ceramics (Barium Zirconates (BaZrO3) or Cerates (BaCeO3) with various dopants) transport hydrogen ions (H+) through a dense ceramic layer, which can operate at lower temperatures (400-650°C). Such cells can produce pure, moisture-free, pressurized hydrogen, enabling a simplification of the balance of plant compared to conventional solid oxide electrolysis systems, hence a reduction in the overall capital and operating costs. For these reasons, proton conducting electrochemical cells present untapped opportunities for hydrogen generation, and separation, as well as for electrochemical conversion and manufacturing.
