title: A highly flexible electrochemical flow cell designed for the use of model electrode materials on non-conventional substrates.
abstract: We present a novel electrochemical flow cell based on a wall-jet configuration to carry out electrochemical investigations under controlled mass transport conditions. The described setup can be applied for investigations similar to those performed with a common rotating disc electrode setup but allows the use of non-conductive and square substrates. This setup thus opens the possibility for the characterization of a new range of materials on a broad range of substrates. Cyclic voltammograms were recorded to assess the cleanliness and good saturation of the cell with inert gas. The performance of the flow cell regarding hydrodynamic experiments was evaluated by probing the oxygen reduction reaction on differently prepared platinum catalysts, including Pt on non-conductive substrates. The high reproducibility of the limiting currents for these samples demonstrates the good functionality, adaptability, and flexibility of the cell.
