Abstract

Metal-supported protonic ceramic fuel cells were prepared, and the effects of a double columnar layer at the cathode side of BaZr_0.44Ce_0.36Y_0.2O₃ (BZCY) on power density and open-circuit voltage (OCV) were studied. The double columnar structure of Pr_0.2Ce_0.8O₂ (PrDC) and BZCY was prepared with pulsed laser deposition. It was found that the insertion of the double columnar layer was highly effective for increasing the power density and OCV. The optimum composition of the double columnar was BZCY:PrDC = 7:3, with a thickness of 200 nm. The power density of PCFCs with the BZCY-PrDC double columnar reached 413 mW/cm², and the OCV was approximately 1.05 V at 873 K, which is six times higher than that of a cell without a functional layer. The high power density of the cell was attributed to the decreased overpotential of the cathode. Therefore, the BZCY-PrDC double columnar layer is effective in expanding the reaction site by increasing the proton concentration at the cathodic interface.

用于 Ni-Fe 金属支撑质子陶瓷燃料电池阴极功能层的 BaZr(Ce,Y)O3-Pr-掺杂 CeO2 双柱体

制备了金属支撑质子陶瓷燃料电池，并研究了 BaZr0.44Ce0.36Y0.2O3 (BZCY) 阴极双柱状层对功率密度和开路电压 (OCV) 的影响。采用脉冲激光沉积法制备了 Pr0.2Ce0.8O2 (PrDC) 和 BZCY 的双柱状结构。研究发现，插入双柱状层对提高功率密度和 OCV 非常有效。双柱状层的最佳组成为 BZCY:PrDC = 7:3，厚度为 200 nm。带有 BZCY-PrDC 双柱状层的 PCFC 功率密度达到 413 mW/cm2，在 873 K 时的 OCV 约为 1.05 V，是不带功能层电池的六倍。电池的高功率密度归功于阴极过电位的降低。因此，BZCY-PrDC 双柱状层通过增加阴极界面的质子浓度，有效地扩大了反应场所。
