【摘要】 对固体氧化物燃料电池（ＳＯＦＣ）进行研制．在ＹＳＺ固体电解质上制备成功Ｌａ０．８Ｓｒ０．２ＭｎＯ３阴极和Ｎｉ－ＹＳＺ陶瓷阳极，并解决了高温无机密封技术难题，组装出平板式ＬＳＭ／ＹＳＺ／Ｎｉ－ＹＳＺ单电池．在９５０℃，Ｈ２为燃料时，电池最大输出功率密度达０．１２Ｗ／ｃｍ２．对阴、阳极性能分析得出，ＬＳＭ电极的电化学性能与国外报道的电极性能相当，电池功率密度较低主要是由Ｎｉ－ＹＳＺ陶瓷电极电化学活性较差和电池内阻（界面接触电阻）较大造成的．更多还原

【Abstract】 The solid oxide fuel cells of planar type(SOFC) have been developed after successfully preparing La 0.8 Sr 0.2 MnO 3 cathodes and Ni YSZ ceramic anodes on YSZ plates and solving the high temperature sealing technical problem. Examination of the single cells fabricated showed that the maximum power output at 950 ℃ for H 2 as fuel and air as oxidant reached 0.12 W/cm 2. It was found that the large polarization overpotential of the Ni YSZ anode and the Ohmic losses of the cells were two main factors responsible for the relative low output power density.更多还原
