用涂布共烧结法制备固体氧化物燃料电池

Slurry Coating and Co-Sintering Used for Perparation of SOFC

以８％Ｙ２Ｏ３稳定的超细ＺｒＯＺ２（８ＹＳＺ）粉末为固体电解质材料，以喷雾热解法制备的超细Ｌａ０．８Ｓｒ１－ｘＭｎＯ３、（２０ＬＳＭ）粉末为空气极电极材料，以ＮｉＯ／８ＹＳＺ粉末为燃料电极原料，采用浆料涂层共烧结法制备电极薄膜，并组装了固体氧化物燃料电池（ＳＯＦＣ）。在Ｈ２－Ｎｉ－８ＹＳＺ－２０ＬＳＨ－Ａｉｒ体系中，分别测定了８００℃用１０００℃时的开路电压及电池Ⅰ—Ⅴ特性曲线。

The electrolyte material is 8 mole percent yttria-stabilized zirconia(8YSZ).The cathode material is ultrafine La xSr 1-x MnO 3(20LSM) powder produced by spray pyrolysis.The anode material is mixture of commercial NiO and 8SYZ powders.The slurry coating and co-sintering is used for preparation of electrode membranes.The solid oxide fuel cell(SOFC) was equipped and its characteristics were determined in H 2-Ni-8YSZ-20LSM-Air system.
