Application of a GaPO4 Crystal Microbalance for the Detection of Coke Formation in High-Temperature Reactors and Solid Oxide Fuel Cells
For the first time, a piezoelectric crystal microbalance sensor based on gallium orthophosphate has been shown to monitor mass deposition at temperatures up to 900 °C, with the ability to detect coke formation on a Ni-modified crystal demonstrated. The work represents a new class of analytical technique capable of studying surface reactions at high temperatures. This is now being funded by the NPL and options for commercialising it are being explored. This work has led to the invited plenary lecture at Electrochem 2011, the UK’s premier electrochemistry conference.
