Fuel Cell Energy Generators PLATINUM CATALYSTS USED in ALTERNATIVE ENERGY SOURCE
Fuel Cell Energy Generators PLATINUM CATALYSTS USED IN ALTERNATIVE ENERGY SOURCE By D. S. Cameron Group Research Centre, Johnson Matthey and Co Limited The steam, in turn, is produced by burning Improvements in the preparation and fossil fuels (coal or hydrocarbons), or by utilisation of platinum metal catalysts nuclear fission. Unfortunately, the processes have now made megawatt scale fuel cell of converting fuel into heat, heat into steam, systems economically viable. The high and steam into electricity involve efficiency thermal efficiency and low pollution losses at every stage. The Carnot cycle characteristics of this novel power source shows that the thermal efficiency of any heat are likely to result in it forming an engine is limited to E where: increasing proportion of the generating capacity utilised for both peaking and intermediate applications. This paper T, and TI being the temperatures, in degrees briejly reviews the development of fuel kelvin, at which heat is supplied to, and cells; it also describes how they work, rejected by, the system. In practice, upper including the function of the catalyst, temperatures are limited to about 500'C and indicates the more important of the (773 K), lower temperatures are at least 30°C many factors which have to be considered (303 K), and efficiencies are limited to a when selecting a commercial system. maximum of 60 per cent.

Environment template (REF5) Institution: Swansea University: Prifysgol Abertawe Unit of Assessment: 28b - Modern Languages and Linguistics (Celtic Studies) a. Overview Staff included in this Unit of Assessment are based within Academi Hywel Teifi or affiliated to it. Established in 2010, it champions the Welsh language throughout the University and includes the Welsh for Adults Centre for south-west Wales and the former Department of Welsh. The research of the Unit specifically focuses on three fields in relation to the Welsh language: its literature, its cultural media and applied linguistics, with more staff currently involved in the first field. The Unit is supported in all activities by the wider structures of the College of Arts and Humanities (COAH). COAH is home to the Research Institute for Arts and Humanities (RIAH) and its Graduate Centre. COAH’s large team of nine staff – director, assistant director, research and administrative officers – support Academi researchers and postgraduates. Two members of the Academi sit on its Management Board and the College’s Research committee. A member of the Academi currently directs the Graduate Centre. Since RAE 2008, these new structures have dramatically transformed the research environment of Welsh and Welsh studies at Swansea for the better. The Unit runs its own seminar series, Seminar y Gymraeg, organised by Academi Hywel Teifi and attended by colleagues from several departments. In addition to Seminar y Gymraeg, our researchers within the Unit are active members of other COAH interdisciplinary research centres and groups, including the Centre for Research into the English Language and Literature of Wales (CREW) and the Language Research Centre (LRC), and attend events with a Celtic Studies theme at other centres such as the Centre for Medieval and Early Modern Research (MEMO). -
Welsh-Medium and Bilingual Education
WELSH-MEDIUM AND BILINGUAL EDUCATION CATRIN REDKNAP W. GWYN LEWIS SIAN RHIANNON WILLIAMS JANET LAUGHARNE Catrin Redknap leads the Welsh Language Board pre-16 Education Unit. The Unit maintains a strategic overview of Welsh-medium and bilingual education and training. Before joining the Board she lectured on Spanish and Sociolinguistics at the University of Cardiff. Gwyn Lewis lectures in the College of Education and Lifelong Learning at the University of Wales, Bangor, with specific responsibility for Welsh language education within the primary and secondary teacher training courses. A joint General Editor of Education Transactions, his main research interests include Welsh-medium and bilingual education, bilingualism and child language development. Sian Rhiannon Williams lectures on History at the University of Wales Institute Cardiff. Her research interests include the history of women in the teaching profession and other aspects of the history of education in Wales. Based on her doctoral thesis, her first book was a study of the social history of the Welsh language in industrial Monmouthshire. She has published widely on the history of Gwent and on women’s history in Wales, and has co- edited a volume on the history of women in the south Wales valleys during the interwar period. She is reviews editor of the Welsh Journal of Education. Janet Laugharne lectures in the Cardiff School of Education, University of Wales Institute Cardiff, and is the School’s Director of Research. She is interested in bilingualism and bilingual education and has written on this area in relation to Welsh, English and other community languages in Britain. She is one of the principal investigators for a project, commissioned by the Welsh Assembly Government, to evaluate the implementation of the new Foundation Stage curriculum for 3-7 year-olds in Wales. -

And thine in close coiled circuits wind Around the needle of my heart. Constant as Daniell, strong as Grove. Ebullient throughout its depths like Smee, My heart puts forth its tide of love, And all its circuits close in thee. O tell me, when along the line From my full heart the message flows, What currents are induced in thine? One click from thee will end my woes.

Fuel cell is an electrochemical energy converter. It converts chemical energy of fuel (H 2) directly into electricity.

Electrochemistry and Fuel Cells: the Contribution of William Robert Grove
Indian Journal of History of Science, 50.3 (2015) 476-490 DOI: 10.16943/ijhs/2015/v50i4/48318 Historical Notes Electrochemistry and Fuel Cells: The Contribution of William Robert Grove Jaime Wisniak* (Received 19 January 2015) Abstract William Robert Grove (1811-1896), a British lawer, judge, and researcher, discovered the voltaic cell that carries his name (more powerful than the Daniell one), the fuel cell, and carried fundamental research in the area of electrochemistry and allied phenomena. His general analysis of physical phenomena may be considered an expression of the first law of thermodynamics and the negation of perpetual motion. Key words: Daniell cell, Electrochemistry, Energy conversion, First law of thermodynamics, Flame electricity, Gas fuel cell, Grove cell, Perpetual motion, Polarization. 1. INTRODUCTION to Grove being appointed to the first professorial chair of the Institution (1841-1846). William Robert Grove1 was born on July 11, 1811, in Swansea in South Wales, the only son The financial needs for growing a long of Anne Bevan and John Grove, a magistrate and family forced him to return to the practice of law; deputy lieutenant of Glamorgan. After receiving in 1853 he became a Q.C.

In 1887, after retirement, he University of Oxford), receiving a B.A. degree in appointed a member of the Privy Council. 1832. He then moved to London to pursue a legal career at Lincoln’s Inn and was called to the bar William Grove passed away on August 1, 1896, after a long illness and was buried at Kensal in 1835.
