Abstract

A tubular proton-conducting fuel cell, anode-supported, was fabricated using dip-coating and followed by the co-sintering of anode and electrolyte at 1500°C. The electrolyte and anode thicknesses are respectively 6 and 500 µm. The outer diameter of the tubular cell is 5.8 mm, featuring an anode porosity of 23%. Ammonia-fueled single cell with Ru-catalyzed internal cracking reactor is operated at various temperatures from 400°C to 600°C. Calculation results indicate that double-ring current collection is an efficient current-collecting mode. At 600°C, the device exhibited a high open-circuit voltage of 1.02 V and a peak power density of 216 mW cm⁻², with a total active area of 2.28 cm². Exhaust gas analysis reveals a 99.13% ammonia decomposition rate at 600°C.

一种具有内陶瓷氨裂解组件的阳极支撑管状质子导体燃料电池

采用浸涂法制备了一种阳极支撑的管状质子传导燃料电池，并在1500℃下对阳极和电解质进行共烧结。电解液和阳极厚度分别为6µm和500µm。管状电池外径为5.8 mm，阳极孔隙率为23%。氨燃料单细胞与ru催化内裂解反应器在400 ~ 600℃的不同温度下运行。计算结果表明，双环集流是一种有效的集流方式。在600℃时，器件的开路电压为1.02 V，峰值功率密度为216 mW cm−2，总有效面积为2.28 cm2。废气分析显示，在600°C时氨分解率为99.13%。
