Standard Practice for Screening Organic Halides Contained in Hydrogen or Other Gaseous Fuels

Importancia y uso:

5.1 Low operating temperature fuel cells such as proton exchange membrane fuel cells require high purity hydrogen for maximum material performance and lifetime. Analysis to at least 0.05 µmol/mol concentration of total halogenated (measured as methyl fluoride) in hydrogen is necessary for assuring a feed gas of sufficient purity to satisfy fuel cell system needs as defined in ISO 14687, SAE J2719, and the California Code of Regulations, or as specified in regulatory codes.

5.2 Although not intended for application to gases other than hydrogen, techniques within this screening method can be applied to other gaseous samples requiring total halogenated hydrocarbon content determination. The method must be validated when used to test fuels or other gaseous samples that may contain interfering compounds.
