Abstract:A steady-state isothermal model is presented for the electrochemical reduction of CO 2 to CO in a microfluidic flow cell. The full cell model integrates the transport of charge, mass, and momentum with electrochemistry for both the cathode and anode. Polarization curves obtained from experiments conducted at different flow rates with varying applied cell potentials are used to determine the kinetic parameters in the electrochemical reaction rate equations. The parameterized model is validated using a different… Show more
The opportunities and challenges for exploiting the production of syngas from the electrochemical reduction of CO2are critically reviewed and analysed.

“…Fuel crossover in the middle channel can be reasonably neglected as mixing of the two streams occurs by transverse diffusion only and is restricted to a thin interfacial region at the center of the channel [1,2]. Furthermore, the electrolyte conductivity in the middle channel is stable due to the excess supporting electrolyte [40]. The charge transport in the middle channel can be calculated without knowing the species distribution in the middle channel.…”
“…Electrofuels synthesised from renewable electricity such as wind or solar can have very low CO 2 footprint, especially when obtained from CO 2 [45][46][47][48][49]. However, in view of life cycle perspective there are some CO 2 emissions associated with renewable power generation (see Table 1) and additional CO 2 emissions are created by applying an electricity-to-electrofuel conversion step.…”
