Microwave sintering is a very interesting subject, which provides an alternative method to overcome problems faced with conventional sintering. This process is very efficient and only requires a few minutes. In this paper, nanocomposite electrodes (Cu0.15Ni0.85-GDC) were sintered at 700 degrees C for 10 mins in a single mode 2.45 GHz microwave oven by the solid state reaction method. The composition influence and the sintering methods on the as-obtained powder were characterized by XRD, SEM and TEM. It was observed that excellent sintering took place. Excellent fuel cell performance was achieved with microwave sintering compared tosamples sintered using conventional sintering. Electrochemical analysis was carried out using AC Impedance technique. This paper reports a new approach to develop a microwave sintered based nanocomposite material, which is more efficient on time and energy. This method can gain significant economical benefits compared to conventional sintered materials for applications in low temperature solid oxide fuel cells (LTSOFC).
微波烧结是一个非常有趣的课题，它提供了一种替代方法来克服传统烧结面临的问题。这个过程非常高效，只需要几分钟。在本文中，通过固态反应法在单模2.45GHz微波炉中于700摄氏度下将纳米复合电极（Cu0.15Ni0.85-GDC）烧结10分钟。通过XRD、SEM和TEM对所得粉末的成分影响和烧结方法进行了表征。观察到发生了优异的烧结。与使用传统烧结法烧结的样品相比，微波烧结实现了优异的燃料电池性能。使用交流阻抗技术进行了电化学分析。本文报道了一种开发基于微波烧结的纳米复合材料的新方法，该方法在时间和能量方面更高效。与用于低温固体氧化物燃料电池（LTSOFC）的传统烧结材料相比，这种方法可以获得显著的经济效益。
