Standard

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).

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).

This part of ISO 14687 specifies the quality characteristics of hydrogen fuel in order to ensure uniformity of the hydrogen product as dispensed for utilization in proton exchange membrane (PEM) fuel cell road vehicle systems.

Introduction
This part of ISO 14687 provides an initial, albeit incomplete, basis for describing a common fuel to be used by proton exchange membrane (PEM) fuel cell applications for stationary appliances in the near term.

This International Standard specifies the essential requirements for fuel cell vehicles (FCV) with respect to the protection of persons and the environment inside and outside the vehicle against hydrogen-related hazards.
It applies only to such FCV where compressed hydrogen is used as fuel for the fuel cell system.
This International Standard does not apply to manufacturing, maintenance, and repair.
The requirements of this International Standard address both normal operating (fault-free) and single-fault conditions of the vehicles.

Preface
This publication represents a standard for safe operation, substantial and durable construction and performance testing of thermally activated pressure relief devices for compressed hydrogen vehicle fuel containers, for the on-board storage of compressed hydrogen for vehicle operation within limitations given below and in the scope of this standard.

This standard is based on proven engineering principles, research and the combined expertise of gas utilities, manufacturers, users, and others having specialized experience.
