| Abstract | A multistep synthesis method is introduced to fabricate high performance IrOx /W-TiO2 catalyst for noble metal reduction in PEM water electrolyzers. The performances of the IrOx/W-TiO2 catalyst for oxygen evolution reaction (OER) are measured in half-cells and single-cells and compared with unsupported IrOx and commercial IrO2. In half-cell tests, IrOx/W-TiO2 displays an improved Ir mass activity compared with the unsupported IrOx, demonstrating a positive effect of the support material. In single-cell tests, the performance of IrOx/W-TiO2 also exceeds both the unsupported and commercial IrO2. The cell voltage reaches 1.602V at 1 A cm(-2) (Nafion 212) with total noble metal loading less than 0.2 mg cm(-2), suggesting that significant Ir reductions are possible by using IrOx/W-TiO2 without sacrificing the cell performance. It also shows improved durability than other unsupported catalysts at reduced Ir loading. In-situ electrochemical test reveals that the performance is associated with the enhanced conductivity of the catalyst layer. (C) 2021 Elsevier Ltd. All rights reserved. |
