A direct borohydride fuel cell with a polymer fiber membrane and non-noble metal catalysts: 点击次数：; 发表刊物：Scientific Reports; 关键字：ELECTROCHEMISTRY MATERIALS CHEMISTRY ELECTRONIC MATERIALS AND DEVICES ENERGY; 摘要：Polymer electrolyte membranes (PEM) and Pt-based catalysts are two crucial components which determine the properties and price of fuel cells. Even though, PEM faces problem of fuel crossover in liquid fuel cells such as direct methanol fuel cell (DMFC) and direct borohydride fuel cell (DBFC), which lowers power output greatly. Here, we report a DBFC in which a polymer fiber membrane (PFM) was used and metal oxides, such as LaNiO3 and MnO2, were used as cathode catalysts, meanwhile CoO was used as anode catalyst. Peak power density of 663 mW·cm−2 has been achieved at 65°C, which increases by a factor of 1.7–3.7 compared with classic DBFCs. This fuel cell structure can also be extended to other liquid fuel cells, such as DMFC.; 论文类型：期刊论文; 学科门类：工学; 文献类型：J; 卷号：567; 期号：2; 页面范围：1-4; 是否译文：否; 发表时间：2012-08-09; DOI码：10.1038/srep00567; 第一作者：Xiaodong Yang; 合写作者：Li Wang,Xiaozhu Wei,Sai Li; 通讯作者：Yuanzhen Chen,Yongning Liu; 发布期刊链接：https://www.nature.com/articles/srep00567
