2 Bacon, Francis Thomas
SUBJECT AREA: Aerospace[br]b. 21 December 1904 Billericay, Englandd. 24 May 1992 Little Shelford, Cambridge, England[br]English mechanical engineer, a pioneer in the modern phase of fuel-cell development.[br]After receiving his education at Eton and Trinity College, Cambridge, Bacon served with C.A. Parsons at Newcastle upon Tyne from 1925 to 1940. From 1946 to 1956 he carried out research on Hydrox fuel cells at Cambridge University and was a consultant on fuel-cell design to a number of organizations throughout the rest of his life.Sir William Grove was the first to observe that when oxygen and hydrogen were supplied to platinum electrodes immersed in sulphuric acid a current was produced in an external circuit, but he did not envisage this as a practical source of electrical energy. In the 1930s Bacon started work to develop a hydrogen-oxygen fuel cell that operated at moderate temperatures and pressures using an alkaline electrolyte. In 1940 he was appointed to a post at King's College, London, and there, with the support of the Admiralty, he started full-time experimental work on fuel cells. His brief was to produce a power source for the propulsion of submarines. The following year he was posted as a temporary experimental officer to the Anti-Submarine Experimental Establishment at Fairlie, Ayrshire, and he remained there until the end of the Second World War.In 1946 he joined the Department of Chemical Engineering at Cambridge, receiving a small amount of money from the Electrical Research Association. Backing came six years later from the National Research and Development Corporation (NRDC), the development of the fuel cell being transferred to Marshalls of Cambridge, where Bacon was appointed Consultant.By 1959, after almost twenty years of individual effort, he was able to demonstrate a 6 kW (8 hp) power unit capable of driving a small truck. Bacon appreciated that when substantial power was required over long periods the hydrogen-oxygen fuel cell associated with high-pressure gas storage would be more compact than conventional secondary batteries.The development of the fuel-cell system pioneered by Bacon was stimulated by a particular need for a compact, lightweight source of power in the United States space programme. Electro-chemical generators using hydrogen-oxygen cells were chosen to provide the main supplies on the Apollo spacecraft for landing on the surface of the moon in 1969. An added advantage of the cells was that they simultaneously provided water. NRDC was largely responsible for the forma-tion of Energy Conversion Ltd, a company that was set up to exploit Bacon's patents and to manufacture fuel cells, and which was supported by British Ropes Ltd, British Petroleum and Guest, Keen \& Nettlefold Ltd at Basingstoke. Bacon was their full-time consultant. In 1971 Energy Conversion's operation was moved to the UK Atomic Energy Research Establishment at Harwell, as Fuel Cells Ltd. Bacon remained with them until he retired in 1973.[br]Principal Honours and DistinctionsOBE 1967. FRS 1972. Royal Society S.G. Brown Medal 1965.

3 Grove, Sir William Robert
SUBJECT AREA: Electricity[br]b. 11 July 1811 Swansea, Walesd. 1 August 1896 London, England[br]Welsh chemist and physicist, inventor of the Grove electrochemical primary cell.[br]After education at Brasenose College, Oxford, Grove was called to the Bar in 1835. Instead of immediately practising, he became involved in electrical research, devising in 1839 the cell that bears his name. He became Professor of Experimental Philosophy at the London Institution from 1840 to 1845; it was during this period that he built up his high reputation among physicists. In 1846 he published On the Correlation of Physical Forces, which was based on a course of his lectures. He returned to the practice of law, becoming a judge in 1871, but retained his interest in scientific research during his sixteen-year occupancy of the Bench. He served as a member of the Council of the Royal Society in 1846 and 1847 and played a leading part in its reform. Contributing to the science of electrochemistry, he invented the Grove cell, which together with its modification by Bunsen became an important source of electrical energy during the middle of the nineteenth century, before mechanically driven generators became available. The Grove cell had a platinum electrode immersed in strong nitric acid, separated by a porous diaphragm from a zinc electrode in weak sulphuric acid. The hydrogen formed at the platinum electrode was immediately oxidized by the acid, turning it into water. This avoided the polarization which occurred in the early copper-zinc cells. It was a very powerful primary cell with a high voltage and a low internal resistance, but it produced objectionable fumes. Grove also invented his "gas battery", the earliest fuel cell, in which a current resulted from the chemical energy released from combining oxygen and hydrogen. This was developed by Rawcliffe and others, and found applications as a power source in manned spacecraft.[br]Principal Honours and DistinctionsKnighted 1872. FRS 1840.
