Electrolyzers/Fuel Cells

This part of IEC 62282 provides the minimum requirements for safety and performance of fuel cell modules and applies to fuel cell modules with the following electrolyte chemistry:
– alkaline;
– polymer electrolyte (including direct methanol fuel cells) 1;
– phosphoric acid;
– molten carbonate;
– solid oxide;
– aqueous solution of salts.

This part of IEC 62282 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 standard applies to systems
- intended for electrical connection to mains direct, or with a transfer switch, or to a standalone power distribution system;
- intended to provide AC or DC power;
- with or without the ability to recover useful heat;

1.1.1
This Standard applies to ac and dc type portable fuel cell power systems, with a rated output voltage not exceeding 600 V, for commercial, industrial, and residential indoor and outdoor use in non-hazardous locations, in accordance with the Rules of the National Electric Code, ANSI/NFPA 70.
1.1.2
This Standard does not apply to portable fuel cell power systems that are
a. Permanently connected (stationary) to either fuel or electric supply;
b. Designed to export power to the grid;

This part of IEC 62282 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. 

IEC 62282-3-100:2012 is applicable to stationary fuel cell power systems intended for indoor and outdoor commercial, industrial and residential use in non-hazardous (unclassified) areas. It contemplates all significant hazards, hazardous situations and events, with the exception of those associated with environmental compatibility (installation conditions), relevant to fuel cell power systems, when they are used as intended and under the conditions foreseen by the manufacturer.

The purpose of this code is to establish the installation requirements for hydrogen generating equipment, hydrogen utilization equipment, hydrogen dispensing equipment, hydrogen storage containers, hydrogen piping systems and their related accessories.
It applies to all gaseous and liquid hydrogen applications except the following:
- The use of hydrogen in petroleum refineries and chemical plants as feedstock and directly in-process production;

IEC 62282-2:2012 provides the minimum requirements for safety and performance of fuel cell modules; it applies to fuel cell modules with or without an enclosure which can be operated at significant pressurization levels or close to ambient pressure. Deals with conditions that can yield hazards to persons and cause damage outside the fuel cell modules. This edition includes the following significant technical changes with respect to the previous edition:
- inclusion of definitions for hazards and hazardous locations based on the IEC 60079 series;

ISO 22734-1:2008 defines the construction, safety and performance requirements of packaged or factory matched hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water to produce hydrogen and oxygen gas.
It is applicable to hydrogen generators that use the following types of ion transport medium:
Group of aqueous bases;
Solid polymeric materials with acidic function group additions such as acid proton exchange membrane (PEM).

ISO/TR 15916:2015 provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). It identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards.
"Hydrogen" in this paper means normal hydrogen (1H2), not deuterium (2H2) or tritium (3H2).

This International Standard specifies the quality characteristics of hydrogen fuel in order to assure uniformity of the hydrogen product as produced and distributed for utilization in vehicular, appliance or other fuelling applications.
This International Standard applies to all modes of transportation and hydrogen fuelling applications (ground, water, air and space).
