Standard Test Method for Determination of Total Organic Halides, Total Non-Methane Hydrocarbons, and Formaldehyde in Hydrogen Fuel by Gas Chromatography/Mass Spectrometry

Importancia y uso:

5.1 Low operating temperature fuel cells such as Proton Exchange Membrane Fuel Cells (PEMFCs) require high purity hydrogen for optimal performance and longevity. Analysis of hydrogen is necessary for ensuring feed gas of sufficient purity to satisfy fuel cell system needs as defined in SAE J2719, ISO 14687 or as specified in regulatory codes.

5.2 Organic halides and formaldehyde can react with the catalyst in Proton Exchange Membranes (PEMs) and non-methane hydrocarbons degrade PEM stack performance.
