Areas of interest
Gareth has established and continues to lead NPL research in electrochemical energy conversion and storage, which is focused on the development of novel in situ measurement techniques, modelling tools and standard test methods to support commercialisation of polymer electrolyte membrane (PEM) fuel cells/electrolysers, and high energy density batteries. Recent highlights include:
- an innovative reference electrode that allows mapping of the spatial variation in electrode potential across the active area of PEM fuel cells and electrolysers
- a novel galvanostatic technique for simultaneous measurement of electrochemical active surface area of each cell in a fuel cell stack
- 3D real time imaging of lithium-ion batteries during thermal runaway
- establishment of standard test methods for characterisation of battery performance and lifetime
- the development of a 3D multiphysics model of PEM fuel cell performance in an accessible software platform
Gareth is also heavily involved in the development and standardisation of novel test methods for materials selection in the oil and gas industry. Recent achievements include:
- the development of a novel method for measurement of pitting susceptibility of materials in representative oilfield environments
- an experimental technique for validation of predictive models of the chemistry of oilfield environments
- a multi-electrode technique for evaluation of the performance of inhibitors for underdeposit corrosion
- the adaptation of the drop evaporation test method to the determination of the threshold temperature for coating of duplex stainless steels in evaporative seawater conditions
Gareth has carried out research, testing, failure analysis and provided expert advice on corrosion and material degradation for a wide range of clients, primarily in the energy sector.
