Standard Practice for Sampling of High Pressure Hydrogen and Related Fuel Cell Feed Gases

Importancia y uso:

5.1  Hydrogen is delivered to mobile and stationary applications at maximum allowable working (MAWP) pressures up to 87.5 MPag (875 barg, 12 700 psig). The quality of hydrogen delivered is a significant factor in maximizing fuel cell efficiency and life span. Contamination can occur during the production of fuel cell feed gases, contaminating storage containers, station tubing, and fuel lines used for fuel delivery. Collection of a representative fuel sample without the introduction of contaminants even as low as parts per billion by volume (ppb(v)) per contaminant during collection is crucial for assessing the quality of fuel in real world applications and ensuring excessive fuel contaminants will not damage fuel cells or internal combustion engines.

5.2 This practice is intended for application to high pressure, high purity hydrogen; however, the apparatus design and sampling techniques may be applicable to collection of other fuel cell feed gases. Many of the techniques used in this practice can be applied to lower pressure/lower purity gas streams.
