Chapter 10: Electrochemical Reactors

An electrolyzer capable of converting CO₂ into carbon-based fuels and chemicals will need to operate at current densities in excess of 200 mA cm⁻² for industrial applications. This chapter provides a comprehensive review of design considerations for electrolytic flow cell reactors capable of operation at these high current densities. We highlight how the dynamic chemical environment at these conditions is differentiated from experimental conditions more common to academic investigations, and provide a survey of reactor architectures that are being investigated for mediating the CO₂ reduction reaction.
