(4) T d = (E b /k B) (Δ S/R- ln P)-1 whereT d is the desorption temperature, E b is the Binding Energy of the H 2 molecule on the system, k B is the Boltzmann constant, P is the pressure, R is the gas constant and S is change in H 2 entropy from liquid to gas phase (obtained from literature). From this equation, the average desorption ...
2.2 Zirconium Dioxide (ZrO 2) At high temperatures (> 650°C), stabilised zirconium dioxide (ZrO 2) exhibits two mechanisms: 1. ZrO 2 partly dissociates producing mobile oxygen ions and therefore becomes a solid electrolyte for oxygen. A ZrO 2 disc coated with porous electrodes connected to a constant
