H impurity's
The impact of impurities varies with the specific equipment used and on the physio-chemical nature of the impurity. For example, hydrogen boilers that combust hydrogen will generally tolerate higher concentrations of impurities than a vehicle using a polymer electrolyte membrane fuel cell (PEMFC) and inert impurities such as nitrogen are usually less harmful than reactive species such as hydrogen sulphide. Webb26 dec. 2024 · The H impurities have a strong influence on the mechanical and thermal properties of the W metal and seriously affect its service life. From first-principles calculations, we studied the influence of interstitial H on the mechanical and thermodynamic parameters such as elastic constant, elastic modulus, free energy, …
