24、N _ FUEL CELL TECHNOLOGIES Part 7-2: Test methods Single cell and stack performance tests for solid oxide fuel cells (SOFC) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nationa
25、l 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
26、 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- governmen
27、tal 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 te
28、chnical 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
29、 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 uni
30、formity, 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
31、) 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 ens
32、ure 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
33、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 Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the re
34、ferenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The
35、 main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated e
36、fforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be tr
37、ansformed into International Standards. IEC TS 62282-7-2, which is a technical specification, has been prepared by IEC technical committee 105: Fuel cell technologies. PD IEC/TS 62282-7-2:2014 6 IEC TS 62282-7-2:2014 IEC 2014 The text of this technical specification is based on the following documen
38、ts: Enquiry draft Report on voting 105/443/DTS 105/498/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of
39、 all parts of the IEC 62282 series, under the general title: Fuel cell technologies, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data
40、 related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. PD IEC/TS 62282-7-2:2014IEC TS 62282-7-2:2014 IEC 2014 7 INTRODUCTION This technical specification describes test
41、 methods for a single cell and stack (denoted as “cell/stack“ hereafter) that is to be employed in power generation systems using solid oxide fuel cells (SOFCs). SOFCs have a broad range of geometry and size. As such, in general, peripherals like current collectors and gas manifolds are unique to ea
42、ch cell or stack and are often incorporated into a cell or stack to form one integrated unit. In addition, they tend to have a significant effect on the power generation characteristics of the cell or stack. This technical specification therefore introduces as its subject “cell/stack assembly units,
43、” which are defined as those units containing not only a cell or stack but also peripherals. PD IEC/TS 62282-7-2:2014 8 IEC TS 62282-7-2:2014 IEC 2014 FUEL CELL TECHNOLOGIES Part 7-2: Test methods Single cell and stack performance tests for solid oxide fuel cells (SOFC) 1 Scope This part of IEC 6228
44、2, which is a technical specification, provides for SOFC cell/stack assembly units, testing systems, instruments and measuring methods, and test methods to test the performance of SOFC cells and stacks. This technical specification is not applicable to small button cells that are designed for SOFC m
45、aterial testing and provide no practical means of fuel utilization measurement. This technical specification is to be used for data exchanges in commercial transactions between cell/stack manufacturers and system developers or for acquiring data on a cell or stack in order to estimate the performanc
46、e of a system based on it. Users of this technical specification may selectively execute test items suitable for their purposes from those described in this technical specification. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and a
