Gas diffusion electrodes (GDEs) promising to use electrochemical reaction of gases at higher rates such as in fuel cells were used for electro‐reduction. Cu powder, Cu and ZnO mixed powder, and CuO/ZnO mixed oxides were examined as the catalysts. The reduction products with Cu‐GDEs in aq. soln. were CO, etc. The purer and the smaller particle size of the Cu powder, it shows the higher activity and efficiency for CO and hydrocarbons formation. reduction can be carried out ca. 100 times greater rate using a GDE than that with a Cu‐foil electrode. With GDEs of the main product was with an efficiency of 17% with selectivity of 88% at With GDEs of reduced by the selectivity became poorer due to additional production of and although the total efficiencies for reduction became 41% at
