1. Scope
This test method describes a procedure for the determination of trace contaminants in hydrogen and related fuel cell feed gases. Gas chromatography/mass spectrometry (GC/MS) is used to separate and determine contaminants in hydrogen, methanol, and other fuel cell feed gases at part per billion (ppb) or lower concentration. It can be applied to other gaseous samples requiring analysis of trace constituents.
Low operating temperature fuel cells such as proton exchange membrane fuel cells (PEFCs) require high purity hydrogen for maximum material performance and lifetime. Analysis to at least low part-per-billion (ppb) concentration of individual contaminants in hydrogen and related fuel cell supply gases is necessary for assuring a feed gas of sufficient purity to satisfy fuel cell system needs. This standard is submitted in fulfillment of this need.
