Ni-YSZ阳极在固体氧化物燃料电池(SOFC)中使用最为广泛,但是存在积碳问题.采用流延-压烧工艺制备NiO-YSZ|| YSZ池阳极支撑型半电池.对NiO-YSZ|| YSZ半电池进行还原,制备Ni-YSZ阳极.以PdCl2为原料,乙醇为表面活性剂,在Ni/YSZ阳极上表面制备纳米Pd功能层,并制备Pd-Ni-YSZ || YSZ || Pd-Ag单电池.通过SEM和XRD对电极进行表征,发现Pd在Ni-YSZ阳极表面以及内部可以形成多维纳米催化层.浸渍量为0.6wt% Pd的单电池,以甲烷为燃料气时,在750℃和800℃功率密度分别达到了360 mW/cm2和446 mW/cm2.在开路电压下,电池的运行23 h,没有出现明显下降和积碳现象.
