镍具有较高的活性,是直接尿素燃料电池(DUFC)理想的非贵金属阳极催化剂。但尿素的电氧化存在较大的过电位。本文中,制备了具有不同Co含量(0、10、20、30和40wt%)的NiCo/C纳米颗粒以提高活性。 在60°C、0.33 M尿素为燃料、O2为氧化剂的条件下,最佳Co含量为10%,最大功率密度为1.57 mW cm-2。 研究了温度和尿素浓度对DUFC性能的影响。此外,直接尿燃料电池在60°C时的最大功率密度为0.19 mW cm−2,开路电压为0.38 V。  
Nickel is an ideal non-noble metal anode catalyst for direct urea fuel cell (DUFC) due to its high activity. However, there exists a large overpotential toward urea electrooxidation. Herein, NiCo/C bimetallic nanoparticles were prepared with various Co contents (0, 10, 20, 30 and 40 wt%) to improve the activity. The best Co ratio was 10% in the aspect of cell performance, with a maximum power density of 1.57 mW cm−2 when 0.33 M urea was used as fuel, O2 as oxidant at 60°C. The effects of temperature and urea concentration on DUFC performance were investigated. Besides, direct urine fuel cell reaches a maximum power density of 0.19 mW cm−2 with an open circuit voltage of 0.38 V at 60°C.
