| 520 | _ | _ | |a Hydrogen is an important energy carrier in the coming future for sustainable energy systems. In particular, "green hydrogen" produced by water electrolysis is considered as an ultimate technology as it can greatly contribute to net-zero CO2 emission. Accordingly, many green hydrogen targets and policies are being set around the world. The EU has announced plans to install 40 GW of green hydrogen electrolysis capacity in Europe by 2030, and Germany plans to produce up to 14 TWh of green hydrogen by 2030.1,2 Polymer electrolyte membrane (PEM) water electrolysis is the most promising system in the field of water electrolyzers because it offers advantages such as a wide operating range, high current density, and compact system design. It is expected to contribute to the production of green hydrogen, but unfortunately, the cost still needs to be reduced tremendously. Electrocatalysts are the most important part to focus on as they are based on platinum group metals (PGMs) and have the potential to reduce the high cost. In particular, iridium, the electrocatalyst for the anode side, is one of the scarcest elements, and its price is continuously increasing with significant fluctuations due to demand and limited production, which may be a bottleneck for large-scale application of PEM water electrolyzers. In this work, the electrocatalysts for oxygen evolution reactions for PEM water electrolysis were explored. Novel nanostructures were synthesized and evaluated as electrocatalysts under acidic conditions. Since iridium is the only element that has reasonable electrocatalytic activity and stability, they are based on iridium as the main element and the research is focused on the better utilization of iridium in electrocatalysts from the structure point of view. The approach was followed by using transition metals to develop the catalyst structure, considering realistic conditions such as material cost. The electrocatalysts were analyzed and studied before and after electrochemical measurements. |
