Research on Sampling and Analysis Methods for Trace Particulate in Hydrogen Fuel

The quality control of hydrogen for fuel cells has an important impact on the scale application of hydrogen energy. The international and China national standards have strict regulations on the content of gas and particulate impurities in hydrogen fuel. Particulate impurity is one of the important causes for the failure of hydrogen fuel cell systems. However, few studies were done on the sampling and analysis of trace particulates in hydrogen fuel, especially in China. It shows that the lack of basic data on particulate impurity is not conducive to the control of trace particulate impurity in hydrogen fuel. The hydrogen refueling station is an important part of the particulate impurity control. It is recommended that various sampling and analysis methods are required for different locations of the hydrogen refueling station system. Future research directions are also proposed, including the establishment of a particulate source analysis database and the development of standards for on-line measurement of particulate in hydrogen fuel, which can provide effective support for the control of trace particulate impurity in hydrogen fuel.
