Development of high performance low operating temperature protonic conducting ceramic electrolysers
iCase Studentship in “Development of high performance low operating temperature protonic conducting ceramic electrolysers”
Academic Supervisor: Prof. Stephen J. Skinner (Imperial)
Industry Supervisor: Dr Man Yi Ho (SLB)
Start Date: October 2024
Duration: 4 Years
Solid oxide proton conducting ceramics, discovered by Iwahara1 over 30 years ago have been extensively investigated for their application in proton conducting fuel cells. The recent and growing interest in the production of green hydrogen, underpinned by international governmental strategies, including the US hydrogen hubs,2 has renewed interest in proton conducting oxides for application in high temperature electrolysers. Proton conducting ceramic electrolysers (PCEC) offer several advantages over the comparable solid oxide electrolyser (SOE), Figure 1, with temperatures compatible with waste heat from industrial processes, thus offering a route to decarbonisation of industrial processes. Whilst the PCEC has been identified as a route to green hydrogen production there are numerous areas for materials and systems optimisation, with mechanistic understanding of the electrode processes at both anode and cathode being of key concern.
Figure 1: Comparison of a) solid oxide and b) solid protonic electrolysis cells
In this PhD project we will focus on developing detailed mechanistic understanding of the operation of composite electrodes consisting of a novel hexagonal perovskite proton conductor with an electronic conducting phase (e.g. Ni) incorporated. These transport processes include ion transport through the oxide, charge transfer across interfaces and both hydrogen and oxygen evolution reactions. Recent developments of the Ba7Nb4MoO203,4 and Ba3NbMoO8.55 compositions have suggested attractive levels of both protonic and oxide ionic transport, but as yet there have been no studies of the electrochemical performance of these materials in devices, nor any understanding of the durability and cyclability of the cells, including materials thermal expansion behaviour. To further develop knowledge of this technology there will be two key aspects to this research project: 1) manufacture and testing of single cells based on the identified hexagonal perovskite compositions, including detailed characterisation of the mechanism of ion transport and subsequent degradation of electrochemical performance, including selection of compatible electrodes and 2) development of new compositions based on the prototypical materials, and engaging with materials discovery approaches such as molecular dynamics and density functional theory calculations to provide predictors for performance. From these studies we will identify the rate limiting electrochemical processes in next generation materials in a planar electrolysis cell.

Entry requirements: Candidates must meet the college requirements
Project summary: Low temperature water electrolysis is key to enabling green hydrogen production at the terawatt scale. Current water electrolyser technologies require extremely pure water, which limits their design flexibility and imposes resource intensive steps of water purification. Direct seawater electrolysis circumvents these obstacles but is currently limited by the poor activity and stability of catalysts in the presence of ions present in seawater. The slow kinetics of the water oxidation at the anode, the major bottleneck for water electrolysers, is exacerbated in in seawater. Chloride ions, abundantly present in seawater, get preferentially oxidized at the anode and their interaction with the catalyst surface triggers oxy-chloride corrosion mechanisms. This project will aim to design catalysts with an anion-rich surface that can repel chloride ions and thus ensure sustained catalytic performance in the presence of seawater. The student will develop expertise in a combination of electrochemical chacterisation methods, time-of-flight mass spectrometry and operando techniques including optical and surface enhanced infrared absorption spectroscopy to track the evolution of the solid-liquid interface as a function of potential.
Shielding Materials for Fusion Energy
iCASE studentship in “Development of fusion-grade cemented WC for shielding applications in compact spherical tokamaks”
Dr Sam Humphry-Baker (Imperial), Dr Florian Bouville (Imperial), and Dr James Wade-Zhu (UKAEA)
Start date: October 2024-October 2025
Duration: 4 years
Entry requirements: A first-class or upper-class second honours degree (or equivalent) in Materials Science and Engineering or a related discipline. A strong background in materials processing and/or characterisation is desired. A demonstrated interest in ceramics and/or materials for fusion will be an advantage.
Funding: 4 years of funding are available for UK Residents (timely applications from exceptional international students will be considered, subject to institutional funding limitations). The funding will cover standard tuition fees, the iCASE UKRI stipend (£21,662 for 2023/24) and project-related costs.
Project summary: The development of advanced radiation shielding materials is critical to enabling safe operation of compact fusion reactors on a commercial basis. Cemented-WC ceramics, which consist of WC particles bonded together with an iron-based binder, are front-running candidate materials due to their excellent thermal, mechanical, and shielding properties. However, the binder may undergo embrittlement, and the WC particles may swell, due to irradiation-induced defect formation. The PhD project will fabricate a new class “fusion grade” cemented-WC composites, which will alleviate these two concerns. This will be achieved by optimising both the composition of the iron-based binder for improved neutron resilience, and the microstructure of the WC grains to accommodate their swelling. Such an approach will yield a material better equipped to withstand the high neutron doses and transmutation effects expected during service. The project will receive support from the UK Atomic Energy Authority in designing, planning, and conducting irradiation damage studies to better understand the irradiation damage response of the fabricated materials.
The UKAEA’s mission is to lead the delivery of sustainable fusion energy and maximise the scientific and economic benefit. This is a response to the national and global need for sustainable and secure low carbon energy supply. The UKAEA will be supporting this project in several ways including:
- Funding towards the project
- Industrial supervision for the PhD student
- Hosting the student for a 3-month secondment on the UKAEA site or at a National Ion-Beam Facility relevant to the project.

Understanding the type, distribution and mechanical properties of interfaces in geological systems.
Supervisors: Prof Finn Giuliani; Dr Katharina Marquart, Department of Materials; Dr Sam Krevor, Department of Earth Science and Engineering
Home Department: Department of Materials at Imperial College London (South Kensington Campus)
Funding and Deadline: To be eligible for support, applicants must be “UK Residents” as defined by the EPSRC1. The studentship is for 3.5 years starting ASAP and will provide full coverage of standard tuition fees and an annual tax-free stipend of approximately £19,668. Applicants should hold or expect to obtain a First-Class Honours or a high 2:1 degree at Master’s level (or equivalent) in Materials Engineering, another branch of engineering or a related science. Funding is through the project InFUSE (Interface with the future: underpinning science to support the energy transition), funded by the EPSRC and Shell.
Project summary: Carbon capture and storage (CCS) provides a very promising solution to sequester current CO2 production and allow critical process that are difficult to decarbonise to continue running into the future. Understanding the suitability of different rock types for CCS requires a detailed knowledge of among other things their mechanical properties both before and after CO2 injection. The mechanical properties of brittle materials are governed by their ability to dissipate energy which is often controlled by the properties of their interfaces. For example, weak interfaces can promote crack deflection and crack bridging mechanisms giving increased performance. These mechanisms have been studied and optimised in many structural ceramic systems however, in geological materials less work has been carried out.
In this project we propose to both measure the distribution of interfaces and interface categories within different rock types and measure the mechanical the properties of individual key interfaces. In this project you will develop skills in micromechanics, high resolution electron microscopy included EBSD and synchrotron techniques at the Diamond Light Source, the UKs national synchrotron facility. This is a key partner in the project and will support the design of novel environments to study samples under operando conditions. This would give unique insight into the microstructure of candidate rock types. This could then potentially be extended to include samples that have been exposed to supercritical CO2. This could be particularly important in basalt rocks with their ability to mineralize CO2. This allows to cracks to fill with newly formed carbonates and silicates on relatively short timescales (~1-2 years). Yet the whole process of reaction driven cracking is not well understood. This is either regarded as beneficial for safety, by preventing leakage, or as detrimental as mineralization may seal fluid paths and thus reduce permeability. It should also be noted that these research techniques are quite general and a secondary program could be applied to completely different brittle material systems, such as the build-up of damage in battery materials leading to performance degradation.
Informal enquiries about the post and the application process can be made to Prof Finn Giuliani by including a motivation letter and CV.
