The solid-electrolyte cell has a sandwich design and uses a solid electrolyte instead of a liquid one to build a gas–solid interface, so a high-purity liquid product solution is obtained directly without ions entering the solution (Xia et al., Nature Energy 2019). The two outer plates are bipolar plates with serpentine gas channels; anion- and cation-exchange membranes and catalyst-loaded gas diffusion layers are placed between the plates and the central part (hot pressing is recommended). A 3 mm thick, 4 cm² cavity in the central part is filled with solid electrolyte (e.g. ion-exchange resin) and pure water flowing through carries the product out of the cell.
A model with a serpentine channel in the central part, for mass-transfer and flow-field development studies.
