Scale-up of a system for hydrocarbon production by electrochemical reduction of CO2. In: Fuel Cells, 9th European Space Power Conference : session 9. St. Rafael, France, June 2011http://hdl.handle.net/10400.9/1336This work addresses the scaling up of a system for electrochemical reduction of CO2 to produce hydrocarbons that can be used as fuel for a regenerative energy storage cycle. Challenges involved in such a task are mentioned. Scalingup results of a system based on electrodes of high surface area with modified copper deposits are described. Current densities around 100 mA/cm2 were obtained. This corresponds to the current density threshold that enables technological applications. At potentials as negative as -1.6 V it was observed that CO2 reduction still dominated over hydrogen evolution reaction.engconference object
