Glossary of fuel cell termsThe Glossary of fuel cell terms lists the definitions of many terms used within the fuel cell industry. The terms in this fuel cell glossary may be used by fuel cell industry associations, in education material and fuel cell codes and standards to name but a few. Activation loss See overpotential Adsorption Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid (adsorbent), forming a film of molecules or atoms (the adsorbate).
Accumulateur nickel-hydrure métalliqueUn accumulateur nickel-hydrure métallique ou NiMH (de l'anglais nickel-metal hydride) est un accumulateur électrique rechargeable utilisant de l'hydrure métallique (composé permettant de stocker de l'hydrogène) et de l'oxyhydroxyde de nickel comme l'électrode. La technologie NiMH est extrêmement répandue dans les accumulateurs portables d'usage courant : les modèles AA/HR6 dont la capacité peut atteindre pour les plus performants ; les modèles AAA/HR3 dont la capacité maximale est de .
Unité multiple électrique à batterievignette| Les Japonais sont les leaders mondiaux dans les trains à batteries avec au moins 23 unités multiples électriques à batterie en exploitation courante, remplaçant les unités multiples diesel (DMU) sur les itinéraires non électrifiés ou les sections de voie non électrifiées. Une unité multiple électrique à batteries (BEMU), automotrice électrique à batteries ou automotrice à accumulateurs est une unité multiple ou un train à entraînement électrique dont l'énergie est produite par des batteries rechargeables entraînant les moteurs de traction.
Split-phase electric powerA split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended single-phase system, while only requiring a single phase on the supply side of the distribution transformer. This system is common in North America for residential and light commercial applications.
Home fuel cellA home fuel cell or a residential fuel cell is an electrochemical cell used for primary or backup power generation. They are similar to the larger industrial stationary fuel cells, but built on a smaller scale for residential use. These fuel cells are usually based on combined heat and power (CHP) or micro combined heat and power (Micro-CHP) technology, generating both power and heated water or air. A commercially working cell is called Eni-Farm in Japan and is supported by the regional government, which uses natural gas to power up the fuel cell to produce electricity and heated water.
Droop speed controlDroop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power produced by the prime mover according to the grid frequency.
