Substituted ceria-based materials for applications in Solid Oxide Fuel Cell electrolytes and electrodes
Partially substituted (or ‘doped’) cerium oxide materials are of great interest for applications in SOFC components. By the careful choice of dopant identity and quantity, doped cerias can be endowed with very high oxygen ion conductivity, electronic conductivity, catalytic activity for reduction-oxidation and reforming reactions, or a combination of all three. We have developed methods for the preparation of high purity doped cerias with nanoscale particles. Impurities – even a few ppm of Si – have a strongly deleterious effect on ionic conductivity at grain boundaries while high surface area nanoparticles are desirable for applications in SOFC anodes where the material must catalyse the fuel oxidation, or reforming, reaction. This presentation will review our very recent work in which two sets of ceria-based materials were prepared for application either as electrolytes or as anode materials in SOFCs. First, the effect of multiple doping of ceria with combinations of Gd, Nd and Sm on oxygen ion conductivity, materials microstructure and, therefore, suitability for use in SOFC electrolytes will be described. A composition was found which shows better performance at intermediate temperatures than singly Gd- or Sm-doped cerias. Second, the use of nanostructured doped cerias, with and without addition of an active metal function, as anode catalysts will be covered and the important effect of preparation method on ultimate performance will be highlighted.
After obtaining his degree in Chemistry at the University of Durham, U.K. Richard Baker worked for three years in research and development at British Steel plc before moving to Imperial College, London to complete his PhD in the School of Chemical Engineering in the area of oxide materials for Solid Oxide Fuel Cells (SOFCs). Three positions over five years as E.U. Marie Curie Postdoctoral Fellow followed at the Institut Politechnique of Grenoble, France; The Department of Ceramics and Glass Engineering, Aveiro, Portugal; and the Department of Inorganic Chemistry, University of Cádiz, Spain during which he worked on fundamental solid state electrochemistry, anode and electrolyte materials for SOFCs and studied the structure-performance relationships in automotive catalysts using transmission electron microscopy (TEM). He was a lecturer and principal investigator at the University of Dundee for five years before joining the School of Chemistry at St Andrews in 2005. He is now a Senior Lecturer and runs a research group whose interests include development and evaluation of new compositions, nanostructures and concepts for SOFCs; heterogeneous catalysts for pollution abatement and energy applications; and nanostructure-property relationships in functional materials using advanced transmission and scanning electron microscopy (SEM, TEM, S/TEM, EDS). He has supervised eight PhD and 7 MSc students to completion and eight postdocs and has published 69 journal articles with ~1600 citations.

Current status of hydrogen and fuel cells in Norway
Norway’s strategy is structured around five closely interrelated themes addressing: (i) energy supply security, (ii) a fully-integrated energy market, (iii) energy efficiency, (iv) decarbonising the economy and (v) research, innovation and competitiveness. Climate change is one of the policy priorities of Norway. The country is a heavy producer of renewable energy and electricity generation that originate almost entirely from hydroelectric power plants (over 99%). There is also a large potential in wind power, offshore wind power and wave power, as well as the production of bio-energy from biomass. Although, Norway has limited resources in solar energy, it is one of the world's largest producers of solar grade silicon and silicon solar cells. Hydrogen Energy has been identified by Norway as an alternative fuel with the potential for a substantial contribution to reduce petroleum dependence and greenhouse gases emissions in the long term. The Norwegian government supports the potential role of hydrogen for Norway in the transition to a zero-emission society [1,2]. In line with the EU, Hydrogen and Fuel Cell Technologies (HFCTs) have been identified as a key area of research priority for Norway [1-3]. For example, the White Paper on Norway’s energy policy  explicitly describes the national hydrogen priorities, which focus on research and development within production, storage and use of hydrogen. Indeed, among the renewable energy sources, HFCTs are considered as a key technology of the 21st century, not only because of its high efficiency in heat and electricity generation, but also because of its potential role in attaining sustainable energy system. It is also envisaged that HFCT will be integrated into “intelligent” energy networks, with conventional and distributed renewable electricity systems. Also, they enable flexible and adaptable fueling strategies, according to local resources, with fossil, bio-fuels or synthetic fuels to reduce impact on air pollution and climate change. For a few years, Norway has put significant effort in HFCT R&D through national and international projects as well as in implementing a hydrogen infrastructure. This presentation will highlight the main HFCT projects in Norway.

Recent Development in Hydrogen Separation and Purification in Pd-based Membrane System
Global climate change and fossil fuel depletion have driven the need to shift energy use from the conventional carbon cycle to hydrogen cycle. One of the prime advantages of consuming hydrogen as a fuel is zero emissions of carbon dioxide and other pollutants. Hydrogen can be produced from fossil fuels, biomass, and hydrocarbons. However, in most conversion processes, hydrogen-rich gases rather than pure hydrogen are produced. When hydrogen is separated from hydrogen-rich gases using membranes, palladium (Pd) has demonstrated its excellent features of high hydrogen permeability and selectivity. In addition to hydrogen separation and purification, Pd-based membranes can also be thought of as a potential tool to fulfill CO2 capture. In this talk, recent development in hydrogen separation and purification in Pd-based membrane systems such as hydrogen permeation, concentration polarization, and membrane permeance measurement will be introduced. The interfacial and bulk mass transfer phenomena of hydrogen in Pd-based membrane system will be underlined. The presentation will also show hydrogen permeation in Pd membrane tube systems approached by computational fluid dynamics (CFD), demonstrating the potential of simulations as a tool to aid in membrane system designs.
