In general, the air cathode of primary Mg-air batteries must form a three-phase (gas-solid-liquid) interface with gas, catalyst/carbon and electrolyte contact to promote the reduction of gaseous oxygen.19,32,36,37,66,68,84,89,202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212...
The ideal gas reduction of the ENASG EOS is used with parameters for water given in Table 1 while the only coefficients needed for air are: Cv,3 = 719 J/kg/K and γ3 = 1.4. Liquid is present but in negligible proportions so mixture equation of state (65) is used in practice. ...
On the one hand, in the procedure of TF-RDE, the reaction gas (H2, O2 or air) is charged into the electrolyte. However, the low solubility of the gas in the electrolyte is very different from the gas concentration in practical application [52]. On the other hand, the catalyst layer ...
