Nernst equation The reversible voltage of hydrogen-oxygen fuel cells under the standard condition (298.15 K, 1 atm, 101,315 Pa) is calculated in Eq. (1.19). For other conditions, the reversible voltage will certainly change. Temperature and gas reactant concentration are two main factors affecti...

More importantly, silicone oil-based materials are nonvolatile and chemical stable towards the ALB systems. The PDMS-based material has received tremendous attention in the field of gas separation because of its high oxygen permeability (PO2 = 600 Barrer), which is derived from the large free ...
Quantum-Mechanical Equation of State of a Hard-Sphere Gas at High Temperature. II As the continuation of a preceding paper, an expansion for the quantum-mechanical free energy F of a hard-sphere gas at high temperature is extended up to ... B Jancovici - 《Physical Review》 被引量: 22...
As the cell is not completely filled with liquid, gas is also present in the cell. The evolved molecular O2 from the catalytic oxide surface dissolves and diffuses through the thin liquid layer, and once the molecular oxygen reaches the gas–liquid interface, it precipitates and induces the ...
41. In particular the chemical potential of LSC-50 bulk oxygen in reference to O2,gas is set using their reported parameters \({\mathrm{\Delta }}h_{\mathrm{O}}^0\),ΔS0 and a (Figure 13a of Mizusaki et al.41). However, we need to make use of bulk defect energies from DFT ...
details will be discussed in the fifth chapter. Surface treatment generally remove the labile oxygen to increase the initial irreversible capacity, such as gas treatment [84,85], acid treatment [104,105], and NH4F treatment [106,107], etc. Qiu et al. [84] increasedoxygen vacanciesthough CO2...
From Equation (1), the amplitude of PT signal is linearly proportional to the length of the HC-NCF. However, the use of a longer HC-NCF increases the gas filling time. The filling time of the HC-NCF is less than 1 min, as has been demonstrated previously with the same type of HC-...
