Mark Cassidy

Dr Mark Cassidy is a Senior Research Fellow within the School of Chemistry at the University of St Andrews. His focus is developing the key interface between strategic research and pre-commercialisation development, accelerating the transfer of results from fundamental discovery towards practical application. He is currently a Co-Investigator on 5 current EPSRC research grants, 3 EU grants and 2 other industrially sponsored grants. He is a member of the Scientific Board of the EPSRC Hydrogen and Fuel Cell Hub and also a member of the American Ceramic Society and the Electrochemical Society.

He is a materials process specialist and has been involved in solid oxide fuel cell (SOFC) research for over 20 years, starting doctoral studies into SOFC fabrication in 1993. He was awarded his Ph.D. in 1997 from Napier University, Edinburgh for the development and demonstration of screen printed electrolytes cofired on supporting tape cast anodes. He has considerable industrial research experience, with 9 years in industrial fuel cell development, holding senior technical positions in a number of leading international SOFC companies, Rolls-Royce (UK), Global Thermoelectric – now Versa Power (Canada) and Ion America – now Bloom Energy (USA), all of which he still actively communicates and collaborates with. Specific areas of interest included functionally graded materials for electrodes, study of microstructural development at interfaces, stabilisation of high performance cathode materials, development of materials for reversible SOFC operation and the separation of the various loss mechanisms within the cell, resulting in 3 patents being granted and further applications ongoing. An important part of his industrial work was liaising with universities and working to identify interesting new science and translate these into technologically relevant components for industrial application and he continues play a role in this liaison from the university side in his current work.

He joined the team at University of St-Andrews as a Senior Research Fellow in 2006 and continues to specialise in ceramic processing and advanced materials with an aim to better understanding process-microstructure-performance relationships. A significant focus of current work is the integration of new materials into electrochemical devices. This revolves around the application of ceramic thick film techniques, especially control of slurry properties (both solvent and water based)and firing techniques to control and engineer microstructures. Example outputs of this work have been integration of ceramic redox tolerant anodes into the complex Rolls-Royce Fuel Cell Systems (RRFCS) geometry with minimal loss in performance and without disturbing the adjacent process steps and working with EU partners on the SCOTAS project to demonstrate infiltrated anodes on porous ceramic supports at the 1kW SOFC system level. This has led to other work on precoating of ceramic particles with nitrate precursors and involvement in the initiation of work into the evolution of nano-catalysts from particle surfaces. Cassidy has also been active in the development of the 2nd generation SOFCRoll, a novel St Andrews SOFC geometry with potential applications in small, portable CHP units running on logistical fuels such as LPG. In addition to his SOFC work he provides advice to researchers outside of the energy group who have materials processing requirements.

In addition to core research activities, Cassidy delivers a 10 lecture course on ceramic processing to final year undergraduates and chemistry researchers new to ceramics. He has also been involved in work applying modern ceramic characterisation techniques and processing knowledge to help unravel technologies and processes used in the manufacture of Orcadian Neolithic pottery, he collaborates on this work with Andrew Appleby, a ceramic artist and archaeologists on Orkney.
