摘要

Abstract > Electrospun La <sub>0.6</sub> Sr <sub>0.4</sub> Co <sub>0.2</sub> Fe <sub>0.8</sub> O <sub>3–</sub> <sub>δ</sub> (LSCF) nanorod cathodes are investigated. Morphological characterization shows that the nanorods are arranged into a 3‐D stochastic structure, with multiple contact points with each other. Experimental characterization of symmetrical button cells through electrochemical impedance spectroscopy demonstrates an electrode polarization resistance R <sub>p</sub> = 3.9 Ω cm 2 at 940 K and R <sub>p</sub> = 10.9 Ω cm 2 at 890 K. The impedance results, measured from 890 K up to 1,200?K, show that the depressed Gerischer behavior is not an intrinsic feature of the electrode, since it appears only at certain well defined temperatures, and then it tends to disappear for other operating temperatures. Equivalent circuit model fitting is accomplished through the depressed Gerischer element, and also through an alternative circuit based on a normal Gerischer coupled to an RQ element. The superior fitting capability of the latter equivalent circuit is demonstrated. The latter circuit allows to assess separately the impedance contribution of the electrode bulk, associated to the Gerischer element, and of the electrode/electrolyte interface, associated to the RQ element. Both the related polarization resistances are larger with the electrospun LSCF 3‐D random nanorod electrode, rather than with an electrospun LSCF electrode with unbroken nanofibers laying neatly in‐plane over the electrolyte. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > Electrom ow La. <sub> 0.6 </ sub> SR. <sub> 0.4 </ sub> CO. <sub> 0.2 </ sub> Fe. <sub> 0.8 </ sub> O. <sub> 3 - </ sub> <sub>Δ</ sub> </ i> （LSCF）纳米棒阴极进行了研究。形态学表征表明，纳米棒被布置成3-D随机结构，彼此具有多个接触点。通过电化学阻抗光谱对称按钮细胞的实验表征证明了电极偏振电阻 R. <sub> p </ sub> </ i> =3.9Ωcm 2 </ sup> 在940 k和 R. <sub> p </ sub> </ i> =10.9Ωcm 2 </ sup> 在890 k下。从890 k测量的阻抗结果，高达1,200 k，表明抑制的Gerischer行为不是电极的内在特征，因为它仅在某些明确定义的温度下出现，然后它往往会消失其他工作温度。等效电路模型拟合是通过凹陷的Gerischer元件完成的，并且还通过基于耦合到RQ元素的普通Gerischer的替代电路完成。表明后者等效电路的卓越拟合能力。后一轮路允许单独评估与Gerischer元件相关联的电极体积的阻抗贡献，以及与RQ元件相关联的电极/电解质界面。电纺LSCF 3-D随机纳米棒电极的相关偏振电阻均较大，而不是用电纺LSCF电极，在电解质上整齐地在平面内铺设不间断的纳米纤维。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24199/'>《Fuel cells》</a> <b style="margin: 0 2px;">|</b><span>2019年第4期</span><b style="margin: 0 2px;">|</b><span>共12页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Costamagna P.&option=202" target="_blank" rel="nofollow">Costamagna P.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sanna C.&option=202" target="_blank" rel="nofollow">Sanna C.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Campodonico A.&option=202" target="_blank" rel="nofollow">Campodonico A.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sala E.
