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.

"WebbUsing a gradient-corrected density functional method, we studied computationally how single impurity atoms affect the structure and the properties of a Ni 4 cluster. H and O atoms coordinate at a Ni–Ni bond, inducing small changes to the structure of bare Ni 4 which is essentially a tetrahedron. For a C impurity, we found three stable structures at … " - H impurity's
