Foreword

GB/T 23751 "micro fuel cell power generation system" consists of the following three parts. --- Part 1. Safety; --- Part 2. Performance test methods; --- Part 3. interchangeability. This part of GB/T 23751 "micro fuel cell power generation system," Part 1. The partial modification using IEC 62282-6-100.2007 "micro fuel cell power systems - Part 1. Safety." This part of IEC 62282-6-100.2007 compared to main changes are as follows. --- Remove the foreword international standards, national standards increase the preface; --- IEC 62282-6-100.2007 international standard referenced in our country who are adopted as a standard, with reference to this part of the country National standards instead of the corresponding international standards; --- International standard reference standard missing IEC 60812, has done a corrected; increase the reference standard. GB/T 7829 and GB/T 20042.1-2005; --- Cancel the fuel cell, the fuel cell power systems, micro fuel cell power generation system, the fuel cell stack, micro fuel cell module Block, the original battery, rated power, fuel leaks, can not contact with the liquid, the normal working conditions and other terms; --- For ease of reference reference Appendix to this part of the modification of using IEC 62282-6-100 CDV files listed in Appendix A, Appendix B, Appendices C and D, taking into account the limitations of boron hydride and butane solid oxide fuel cell development of two kinds of miniature, did not use Appendix E, Appendix F, Annex G and Annex H; --- 7.3.12 type test in the emission test to selectively type tests; --- Individual editorial changes. This section in Appendix A, Appendix B, Appendix C and Appendix D are normative appendix. This part is proposed by the China Electrical Equipment Industrial Association. This part of the National Standardization Technical Committee of the fuel cell (SAC/TC342) centralized. This section is drafted. Beijing speeding Green Energy Power Technology Co., Ltd., Beijing Electrical Machinery Industry Technology Research Institute of Economy, Branch School of Dalian Institute of Chemical Physics. The main drafters of this section. Zhang Lifang, Lu Chen Yu, Zhang Dai, Guo Liping, Wang Su force, Tu Ying and so on. Micro fuel cell power generation system Part 1. Safety
