以丁烷为燃料的便携直接火焰固体氧化物燃料电池堆的研究(英文)

以丁烷液化气为燃料,以固体氧化物燃料电池为电源,可以进行全天候的充电,是未来理想的充电模式。研究了以丁烷为燃料的可以便携的直接火焰燃料电池堆。该电池结构和电性能分别用扫描电子显微镜SEM和电化学工作站进行了表征。该电池堆由3片以Ni/YSZ为阳极支撑形的单电池构成。该电池堆操作开路电压为2.1 V,最大输出功率为0.24 W,可带动小风扇连续运行超过4 h。运行4 h后电池阳极没有积炭发生,说明该电池可以连续运行多个小时,可用作便携充电电源。

The study of portable direct-flame solid oxide fuel cell (DF-SOFC) stack with butane fuel

In this study, a portable direct-flame solid oxide fuel cell (DF-SOFC) stack has been demonstrated using the conventional butane gas as fuel. The stack is constructed by bundles of the 3 single cells in a series with conventional Ni/YSZ anode. The fuel cell structure and performance are characterized by scanning electron microscopy (SEM) and electrochemical workstation, respectively. The results show that the stack presents an open circuit voltage (OCV) of about 2.1 V and an output power of 0.24 W, which powers an USB fan in 4 h. The cell voltage is quite stable for 4 h, moreover, no carbon deposition is found in the anode layer. This indicates that the DF-SOFC stack can be used for portable applications.
