Fuel Cell

IEC 62282-3-100:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62282-3-100:2019 applies to stationary packaged, self-contained fuel cell power systems or fuel cell power systems comprised of factory matched packages of integrated systems which generate electricity through electrochemical reactions. This document is applicable to stationary fuel cell power systems intended for indoor and outdoor commercial, industrial and residential use in non-hazardous areas. This second edition cancels and replaces the first edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition: a) recognition that fuel carrying components qualified to leakage standards (soundness) need not be considered as potential flammable leak sources; b) new annex for small power systems; and c) clarifications for numerous requirements and tests.

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 These requirements can be superseded by other standards for equipment containing fuel cell modules as required for particular applications.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 62282­2:2012: - 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 62282­3-100; - 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.

IEC 60050-485:2020 gives the general terminology used in fuel cell technologies, as well as general terms pertaining to specific applications and associated technologies. This terminology is consistent with the terminology developed in the other specialized parts of the IEV. It has the status of a horizontal standard in accordance with IEC Guide 108.
