ISO 14687 Hydrogen Fuel – Product Specification

This first edition of ISO 14687 cancels and replaces ISO 14687-1:1999, ISO 14687-2:2012 and ISO 14687-3:2014. It also incorporates the Technical Corrigenda ISO 14687-1:1999/Cor 1:2001 and ISO 14687-1:1999/Cor 2:2008. Part 1: ISO 14687-1 All applications except proton exchange membrane (PEM) fuel cells for motor vehicles Part 2: ISO 14687-2 Proton exchange membrane (PEM) fuel cell applications for road vehicle Part 3: ISO 14687-3 Proton exchange membrane (PEM) fuel cell applications for stationary applications This document has been mainly revised based on the research and development of PEM fuel cells focusing on the following items: · — PEM fuel cell catalyst and fuel cell tolerance to hydrogen fuel impurities; · — effects/mechanisms of impurities on fuel cell power systems and components; · — impurity detection and measurement techniques for laboratory, production and in-field operations; · — fuel cell vehicle demonstration and stationary fuel cell demonstration results. The grade D and the grade E of this document are intended to apply to PEM fuel cells for road vehicles and stationary appliances respectively. These aim to facilitate the provision of hydrogen of reliable quality balanced with acceptable lower cost for the hydrogen fuel supply. This document reflects the state of the art at the date of its publication, but since the quality requirements for hydrogen technology applications are developing rapidly, this document may need to be further revised in the future according to technological progress.
