WitrynaThe impact of some impurities like carbon monoxide, formic acid, or formaldehyde is reversible with PEMFC performance recovering once the supply of impurity is removed. Other impurities, for example sulphurous compounds, may cause irreversible degradation. [5] The permissible limits of hydrogen impurities are shown below. Witrynaapplications in a crystal. While high thermal conduc-tivity helps to deport the energy to a heat sink, the low thermal conduction is favourable to heighten the ﬁgure ofmeritofalloys[20]. Thermal conductivity is one of the most important parameter of the material(s) used under variable thermal conditions. In the present work,
