- Топливный бак; отсек топливного бака; топливный элемент 239
- British scientist sir william grove invented this device in 1839. noting that water could be split into hydrogen and oxygen by electrolysis, he reversed the procedure, creating an electrochemical device that combined hydrogen and oxygen to produce electricity with water and heat as by-products. no other energy generation technology offers the same combination of benefits. the process is clean, quiet, highly efficient, and will generate power for as long as fuel is supplied, but the technology remained experimental until the late 20th century. currently (2008) the cruise industry is interested in the possibility of improving passenger comfort with a silent, non-polluting power source that produces no detectable exhaust heat, while most of the world’s navies have active fuel cell programs, especially for submersibles. the hellenic navy class 214 submarine has a fuel cell-generated power supply that allows it to cruise under water for up to three weeks without resurfacing. by contrast, conventional dieselelectric submarines typically deplete their batteries after a few days cruising. in addition, the fuel cell makes the submarine virtually undetectable. the u.s. and other navies are also looking into fuel cell propulsion for surface warships. in addition to the foregoing advantages are reduced fuel consumption and the potential to have a number of separate units to provide redundancy in case of combat damage.
- An electrical cell that converts the intrinsic chemical free energy of a fuel into direct-current electrical energy in a continuous catalytic process. fuel cells extract the chemical energy bound in fuel and, in combination with air as an oxidant, transform it into electricity. researchers are hoping to develop fuel cells that could take the place of combustion engines, thereby reducing the world dependence on fossil fuels.
- A fuel cell generates electricity in a direct and continuous way from the controlled electrochemical reaction of hydrogen or another fuel and oxygen. with hydrogen as fuel it emits only water and heat (no co) and the heat can be utilized (see cogeneration).

- A fixed-length data packet transmitted in certain digital systems such as atm.
- A general term for the anatomical units of plant tissue, including wood fibers, vessel members, and other elements of diverse structure and function.
- A tiny unit of matter which is the base of all plant and animal tissue (note: for other terms referring to cells, see words beginning with cyt-, cyto-.) comment: the cell is a unit which can reproduce itself. it is made up of a jelly-like substance (cytoplasm) which surrounds a nucleus and contains many other small structures which are different according to the type of cell. cells reproduce by division (mitosis) and their process of feeding and removing waste products is metabolism. the division and reproduction of cells is the way the human body is formed.
- An air in the mastoid process
- Комплекс, производственная структура (напр., гибкий производственный модуль)
- The most basic, self-contained unit that contains the appropriate materials, such as plates and electrolyte, to produce electricity.
- A small, usually microscopic, membrane-bound structure that is the fundamental unit of all living things. organisms can be made up of one cell (unicellular; bacteria, for example) or many cells (multicellular; human beings, for example, which are made up of an estimated 100,000 billion cells.)
- A small structural unit, surrounded by a membrane, making up living things.
Cell, английский
Cell (battery), английский
- A single unit of an electrochemical device capable of producing direct voltage by converting chemical energy into electrical energy. a battery usually consists of several cells electrically connected together to produce higher voltages. (sometimes the terms cell and battery are used interchangeably). see also photovoltaic (pv) cell.
- A single unit of an electrochemical device capable of producing direct
Cell address, английский

Cell adhesion, английский
The bonding of cells to surfaces or to other cells. protein molecules at the surface of cells are generally the glue involved in cell adhesion.
Cell array, английский
Cell barrier, английский
- A very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell. the barrier inhibits the movement of electrons from one layer to the other, so that higher-energy electrons from one side diffuse preferentially through it in one direction, creating a current and thus a voltage across the cell. also called depletion zone or space charge.
- A very thin region of static electric charge along the interface of the positive
Cell block, английский

Cell delay variation tolerance, английский
Устойчивость к вариации задержки ячеек
Cell directory service, английский
A service that enables dce clients to locate compatible servers.
Cell division, английский
The way in which a cell reproduces itself. mitosis, meiosis
Cell envelope, английский
The combination of external cellular structures (e.g., plasma membrane, cell wall, outer membrane, glycocalyces) that collectively contain the cytoplasm and internal structures of a cell

Electrolysis, английский
- The decomposition of a chemical compound into its constituent parts by the passage of an electric current; this action leads to the decomposition of metals.
- The destruction of tissue such as unwanted hair by applying an electric current
- A chemical reaction caused by the passage of electricity from one electrode to another.
Electrochemical, английский
Electricity, английский
- Электричество
- Energy resulting from the flow of charge particles, such as electrons or ions.
- The movement of electrons (a subatomic particle), produced by a voltage, through a conductor.
- Energy resulting from the flow of charged particles, such as electrons or ions.
- The fl ow of passing charge through a conductor, driven by a difference in voltage between the ends of the conductor. electrical power is generated by work from heat in a gas or steam turbine or from wind, oceans or falling water, or produced directly from sunlight using a photovoltaic device or chemically in a fuel cell. being a current, electricity cannot be stored and requires wires and cables for its transmission (see grid). because electric current fl ows immediately, the demand for electricity must be matched by production in real time.

- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).
