“…The results shows that (i) the effect of changing T is small, (ii) changing ε / τ or d p has a large effect when the parameter has a low value, but a low effect when they are above about 0.2 and 1 µm, respectively, i.e., at about the standard values they are assigned (common values for the ε / τ fraction is 0.1 to 0.2 , , and for the pore diameter it is 0.13 µm to 1.5 µm , , ), 3) the CO mole fraction is proportional to the CO mole fraction in the channel, current density and electrode depth. Thus, in order to minimize the CO mole fraction at the electrode‐electrolyte interface, ε / τ and d p must be above a certain value while d e should be small.…”

“…One approach to model co‐electrolysis is to assume that only reaction 15 occurs at the interface and that subsequently CO 2 is converted to CO via the water‐gas shift reaction . Another approach is to assume that both reactions occur at the interface and include a parameter β , that determines the fraction of the interface surface available for H 2 O electrolysis . In this approach, the electrical current is divided between the two reactions depending on the mole fraction of CO 2 and H 2 O at the interface.…”

“…The typical electrochemical reaction does not significantly affect the flow rate of the electrode. However, it will affect the overall reaction according to the flow given that the cathode reaction as the rate limiting step and considering that the key reaction occurs in the cathode of the RWGS reaction for the H 2 OeCO 2 coelectrolysis process [8,28]. A kinetic analysis for RWGS is necessary in this case, and further experiments accordingly are planned.…”

“…Similarly, when doubling the current density to 300 mA/cm 2 , a small ratio of H 2 :CO = 0.67 is observed (with production rates of 0.73 ml/min. Some authors suggest that a maximum of 10% of CO is produced by RWSR at 800ºC [35] while others conclude that only at high limiting current densities the CO 2 contributes to the electrochemical performance and the main production of CO is due to the thermo-chemical path [36] . cm 2 of CO).…”
