Standard Practice for Visualizing Particulate Sizes and Morphology of Particles Contained in Hydrogen Fuel by Microscopy

Importancia y uso:

5.1 The particulates in hydrogen fuel for fuel cell electric vehicles (FCEV) and gaseous hydrogen powered internal combustion engine vehicles may adversely affect pneumatic control components, such as valves, or other critical system components. Knowing the sizes and morphology of particulates in the hydrogen fuel is important to ensure that the fuel meets the quality requirements as specified by ISO 14687, SAE J2719, or other hydrogen fuel quality specifications.

5.2 The visualization of the size and morphology of particles is an important tool for determining particle origin as well as for devising particle formation reduction strategies.

5.3 Although not intended for application to gases other than hydrogen fuel, techniques within this practice can be applied to gas samples requiring determination of particulate concentration.
