摘要：
Improving water transport behavior within the anode catalyst layer is an important research topic for anion-exchange membrane (AEM) fuel cells. For proton-exchange membrane fuel cells (PEMFCs), the catalyst layer microstructure has been found to significantly influence the water management, while there is a lack of study on the anode catalyst layer for AEM fuel cells. In this work, we utilize the hydrogen oxidation reaction (HOR) activity difference between Pt/C and PtRu/C catalysts to design anode dual catalyst layers (ADCLs) to improve the water management. The results indicate that the ADCL with the PtRu/C layer close to the gas diffusion layer and the Pt/C close to the AEM form a reactivity gradient that is opposite to the water gradient in the PtRu/C or Pt/C catalyst layer, leading to better water transport in the anode. At 30℃ and a relative humidity of 100%, the maximum peak power density was achieved as 88.1mW/cm2. The results of this study will provide a novel idea for the design of anode catalyst layers in AEM fuel cells. © 2022, Editorial Board of Journal of Tianjin University(Science and Technology).
