Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description | This project has pushed back the boundaries of what we know about how fuel cells operate. We have developed a range of novel diagnostic techniques that allow us to 'look inside' and 'see' what is happening in these complex devices. This has allowed us to develop new ways of operating fuel cells that give longer life and better performance. |
Exploitation Route | As a consequence of this project, Intelligent Energy (the UK's leading fuel cell hardware manufacturer) is currently using techniques developed in the project to understand the role of water in fuel cell operation. We have published extensively and the broader scientific community is adopting our methods. |
