Exploded view of a CO2 electrolyser stack — flow plates, porous gas diffusion and catalyst layers either side of a proton-conducting membrane, with the external electron path above. CO2 enters on the left and the product stream leaves on the right, labelled carbon monoxide, formate, hydrocarbons and alcohols.

CO₂ Fuel Cells: Turning a Greenhouse Gas into Stored Power

Metal–CO₂ cells turn carbon dioxide from waste into an active reactant — reducing it at the cathode while storing energy at high density. Where the science stands, and why the remaining bottlenecks are, above all, materials problems.
