The recycling of waste material has been considered an attractive source for energy production. It is much better to reuse waste batteries than dumping them into landfills. Some advantages that recycling offers include the reduction of pollution load and conservation of natural resources. In the current studies, waste lead acid batteries were used for the production of composite materials i.e.,Pb_0.1Cu_0.4Zn_0.5O_3-δ, Pb_0.2Cu_0.3Zn_0.5O_3-δ and Pb_0.3Cu_0.2Zn_0.5O_3-δ. Recycling of lead acid battery was a difficult job to develop the cost-effective anode material for low temperature solid oxide fuel cell. The structural and morphological properties were examined by XRD and SEM. Thermal stability was analyzed by TGA. The nature of metal oxide bonding in ceramic composites was investigated by FTIR spectra. Electrochemical investigations were carried out using DC four probes and fuel cell testing unit. Average crystalline size was found to be in the range 45–69 nm. SEM images show the porosity of material which is favorable for the diffusion of gases. Maximum conductivities 5.1S/cm, 4.2S/cm and 2.54S/cm have been achieved for Pb_0.3Cu_0.2Zn_0.5O_3-δ, Pb_0.2Cu_0.3Zn_0.5O_3-δ and Pb_0.1Cu_0.4Zn_0.5O_3-δ, respectively. Maximum power density (755 mW/cm²) and high OCV 1.06 V has been obtained using hydrogen as a fuel at 600 °C. Lower activation energy (0.35ev) confirms that Pb_0.3Cu_0.2Zn_0.5O_3-δ is the best candidate for electrochemical conversion of hydrogen fuel into useful electricity.

废料的回收被认为是一种有吸引力的能源生产来源。与将废旧电池倒入垃圾填埋场相比，重复使用废旧电池要好得多。回收利用提供的一些优势包括减少污染负荷和保护自然资源。在当前的研究中，废铅酸电池被用于生产复合材料，即Pb _0.1 Cu _0.4 Zn _0.5 O3 _-δ，Pb _0.2 Cu _0.3 Zn _0.5 O3 _-δ和Pb _0.3 Cu _0.2 Zn _0.5 O _{3- δ}。铅酸电池的回收是开发用于低温固体氧化物燃料电池的具有成本效益的负极材料的一项艰巨的工作。通过XRD和SEM检查结构和形态特性。通过TGA分析热稳定性。通过FTIR光谱研究了陶瓷复合材料中金属氧化物键合的性质。使用直流四个探针和燃料电池测试装置进行了电化学研究。发现平均晶体大小在45-69 nm之间。SEM图像显示出有利于气体扩散的材料的孔隙率。Pb _0.3 Cu _0.2 Zn _0.5 O3 _-δ，Pb _0.2 Cu _0.3的最大电导率达到5.1S / cm，4.2S / cm和2.54S / cmZn _0.5 O3 _-δ和Pb _0.1 Cu _0.4 Zn _0.5 O3 _-δ。使用氢气作为燃料在600°C时已获得最大功率密度（755 mW / cm ²）和OCV高1.06V。较低的活化能（0.35ev）证实Pb _0.3 Cu _0.2 Zn _0.5 O3 _-δ是将氢燃料电化学转化为有用电的最佳候选者。
