Electrochemical Reduction of Oxygen and Nitric Oxide on Mn-Based Perovskites with Different A-Site Cations

Figure 1

A sketch of a setup for measurements on cone-shaped electrodes. The setup is used for evaluating the ability of electrode materials to electrochemically reduce either oxygen (not shown) or nitric oxide. The setup is a pseudo-three-electrode setup as the size of the counter/reference is many times larger than that of the working electrode (the cone). It is seen that the nitric oxide is reduced to nitrogen and oxide anions, at the cone-shaped electrode. The setup is a two-atmosphere setup.
