摘要/Abstract

摘要：

单位化再生燃料电池（URFC）是一种可以作为燃料电池（FC）或水电解（WE）进行可逆工作的装置。该装置的重要组成部分是膜电极组件（MEA）。因此，本研究旨在比较使用单层和三层催化剂电极的MEA性能结果。本研究测量了电化学表面积（ECSA）、电化学阻抗谱（EIS）、X射线衍射分析（XRD）和X射线荧光分析（XRF）。此外，还测量了MEA的往返效率（RTE）以及其在FC和WE模式下的性能。对比结果显示，三层催化剂电极的Pt-Ru/C和Pt/C的ECSA值高于单层催化剂电极。该结果得到了XRD和XRF电极表征数据的支持。Pt-Ru/C和Pt/C三层催化剂电极的电导率值也高于单层催化剂电极，使用三层催化剂MEA的URFC性能在所有MEA的URFC性能中具有最高的RTE值，在4 mA·cm^-2的电流密度下为100%。

Abstract:

A unitized regenerative fuel cell (URFC) is a device that may function reversibly as either a fuel cell (FC) or water electrolysis (WE). An important component of this device is the Membrane electrode assembly (MEA). Therefore, this study aimed to compare the performance outcomes of MEA using electrodes with single and three catalyst layers. This study measured Electrochemical Surface Area (ECSA), Electrochemical Impedance Spectroscopy (EIS), X-ray Diffraction analysis (XRD), and X-ray Fluorescence (XRF). Furthermore, the round-trip efficiency (RTE) of the MEA, as well as the performance in FC and WE mode, was measured. In comparison, The ECSA values of Pt-Ru/C and Pt/C with three catalyst layers were higher than the single catalyst layer. This result was supported by electrode characterization data for XRD and XRF. The respective electrical conductivity values of Pt-Ru/C and Pt/C with three catalyst layers are also higher than the single catalyst layer, and the performance of URFC using MEA with three catalyst layers has the highest value of RTE among the MEA performances of URFC, which is 100% at a current density of 4 mA·cm^-2.
