Fuel cell technologies - Part 5-1: Portable fuel cell power systems - Safety

This part of IEC 62282 covers construction, marking and test requirements for portable fuel cell power systems. These fuel cell systems are movable and not fastened or otherwise secured to a specific location. The purpose of the portable fuel cell power system is to produce electrical power. This standard applies to a.c. and d.c. type portable fuel cell power systems, with a rated output voltage not exceeding 600 V a.c., or 850 V d.c. for indoor and outdoor use. These portable fuel cell power systems are not to be used in hazardous locations as defined by IEV 426-03-01 unless additional protective measures are added in accordance with IEC 60079-0. This standard does not apply to portable fuel cell power systems that are a) permanently connected (hard wired) to the electrical distribution system, b) permanently connected to a utility fuel distribution system, c) exporting power to the grid, d) for propulsion of road vehicles, e) intended to be used on board passenger aircraft. Fuel cells that provide battery charging for hybrid vehicles where the battery provides power and energy for propulsion of the vehicle are not included in the scope of this standard The following fuels and fuel feedstocks are considered within the scope of this standard: - natural gas; - liquefied petroleum gas, such as propane and butane; - liquid alcohols, for example methanol, ethanol; - gasoline; - diesel; - kerosene; - hydrogen; - metals (e.g. Mg, Al or Zn) or metal alloys immersed in electrolyte (e.g. aqueous solutions of salts or alkali) in air or oxygen; - chemical hydrides. This standard does not preclude the use of similar fuels or oxidants from sources other than air provided the unique hazards are addressed through additional requirements.

Tehnologija gorivnih celic - 5-1. del: Naprave s prenosnimi gorivnimi celicami - Varnost

Ta del standarda IEC 62282 zajema zahteve za gradnjo, označevanje in preskušanje naprav s prenosnimi gorivnimi celicami. Te naprave z gorivnimi celicami so premične in niso pritrjene ali drugače nameščene na določeni lokaciji. Naprave s prenosnimi gorivnimi celicami so namenjene proizvodnji električne energije. Ta standard se uporablja za notranje ali zunanje naprave s prenosnimi gorivnimi celicami z izmenično ali enosmerno napetostjo, katerih nazivna izhodna efektivna napetost je manjša od 600 V izmenično ali 850 V enosmerno. Te naprave s prenosnimi gorivnimi celicami se ne smejo uporabljati na nevarnih lokacijah iz standarda IEV 426-03-01, razen če se sprejmejo dodatni zaščitni ukrepi v skladu s standardom IEC 60079-0. Ta standard se ne uporablja za naprave s prenosnimi gorivnimi celicami, a) ki so trajno priključene na sistem za distribucijo električne energije, b) ki so trajno priključene na sistem za distribucijo goriva, c) ki izvažajo električno energijo v omrežje, d) za pogon cestnih vozil, e) za uporabo na potniških letalih. Gorivne celice, ki omogočajo polnjenje akumulatorja hibridnih vozil, pri katerih akumulator zagotavlja električno energijo za pogon vozila, ne spadajo na področje uporabe tega standarda. Na področje uporabe tega standarda spadajo naslednja goriva in energenti: – zemeljski plin; – utekočinjeni naftni plini, kot sta propan in butan; – tekoči alkoholi, npr. metanol, etanol; – bencin; – dizelsko gorivo – kerozin; – vodik; – kovine (npr. Mg, Al ali Zn) ali kovinske zlitine, potopljene v elektrolit (npr. vodne raztopine soli ali alkalij) v zraku ali kisiku; – kemični hidridi. Ta standard ne izključuje uporabe podobnih goriv ali oksidantov iz drugih virov razen zraka, če se posebne nevarnosti obravnavajo v dodatnih zahtevah.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
