| Description | So far this project has allowed us to develop correlative metrology techniques for the analysis of solid oxide fuel cells. This includes the ability to examine the temperature distribution in electrode materials and relate this to strain within the structure. We have also developed an in-situ SOFC cell capable of viewing, with an infrared thermal camera, the temperature distribution within an operational system. We will use these results to inform model development in the next phase of work. |
| Exploitation Route | Our thermal imaging technique will provide unparalleled insight into the internal workings of SOFCs and allow advanced models describing electro-thermal operation to be developed and validated, so leading to the development of commercial SOFC technology. |

| Description | Findings of the operation of solid oxide fuel cell materials under thermal gradients are being communicated to out industrial collaborator, Ceres Power, and we have recently applied for a Supergen H2FC Early Career Researcher award with Ceres to apply thermal imaging alongside X-ray computed tomography to help understand how electrodes function in devices. |
