IEC 62282-2-100:2020提供了燃料电池模块的构造、正常和异常条件下的运行以及测试的安全相关要求。本文件涉及可能对人员产生危险并导致燃料电池模块外部损坏的条件。如果燃料电池模块内部的损坏不会导致模块外部的危险，则本文件未涉及防止损坏的保护。这些要求可以被包含特定应用所需的燃料电池模块的设备的其他标准所取代。 第一版取消并取代了2012年发布的IEC 62282-2。本版本包括以下与IEC 62282-2:20 12相关的重大技术变更: ？更新定义，特别是用于正常操作的燃料电池模块；？解决了正常和异常运行下的泄漏值； ？包括延迟点火测试； ？已包括限制气体泄漏的保护措施； ？更新了带电部件与SELV之间的绝缘要求； ？对通用安全策略进行了修改，以反映不同应用标准的需求；这些修改符合对IEC 62282--3--100的类似修改； ？修改了电气元件条款，以反映不同应用标准的需求；这些修改符合对IEC 62282-3-100的类似修改； ？已引入作为模块一部分的保护接地或作为安装内措施的连接； ？介电强度测试已通过参考IEC 62744-1适用于高达1 000 V交流电/1 500 V直流电的电压； ？新增了“压降法”泄漏试验方法； ？增加了一个新的附件，涉及本文件中涉及的重大危害、危害情况和事件，并与4.1（一般安全策略）相关联。

IEC 62282-2-100:2020 provides safety related requirements for construction, operation under normal and abnormal conditions and the testing of fuel cell modules. This document deals with conditions that can yield hazards to persons and cause damage outside the fuel cell modules. Protection against damage inside the fuel cell modules is not addressed in this document, provided it does not lead to hazards outside the module. These requirements can be superseded by other standards for equipment containing fuel cell modules as required for particular applications.
This first edition cancels and replaces IEC 62282-2, published in 2012. This edition includes the following significant technical changes with respect to IEC 62282-2:2012:
？ update of definitions, in particular fuel cell module for normal operation;
？ leakage values under normal and abnormal operation have been addressed;
？ a delayed ignition test has been included;
？ protective measures to limit gas leakage have been included;
？ the requirements for insulation between live parts and SELV have been updated;
？ the general safety strategy has been modified to reflect the needs for different application standards; the modifications are in line with similar modifications made to IEC 62282--3--100;
？ the electrical components clause has been modified to reflect the needs for different application standards; the modifications are in line with similar modifications made to IEC 62282-3-100;
？ protective earthing as part of the module or bonding as a measure within the installation has been introduced;
？ a dielectric strength test has been completely updated by referring to IEC 62744-1 for voltages up to 1 000 V AC/1 500 V DC;
？ a new “pressure drop method” leakage test method has been included;
？ a new Annex addressing significant hazards, hazardous situations and events dealt with in this document, and linked to 4.1 (General safety strategy) has been added.
