摘要

Abstract >Several studies relying on the improvements to the important oxygen reduction reaction (ORR) activity for increasing the performance of fuel cells have been reported. However, the application of catalyst conditions used for realizing the excellent activity in a half‐cell to a single‐cell does not guarantee the translation of the excellent performance. Therefore, we investigated the performance characteristics of various types of commercially available catalysts, including alloy catalysts, and compared the trends between the half‐cells and single‐cells using linear scan voltammetry (LSV), polarization curves (IVP), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) measurements. Furthermore, regression analysis was performed to identify the influential factors for examining the complex relationship between the half‐cell and single‐cell performance parameters. The study reveals, that it is highly challenging to express the performances of the catalyst and single‐cell using isolated factors. Additionally, even though the measured activity of the catalyst in a half‐cell is higher than that in the other half‐cells, the difference does not manifest significantly in the single‐cell when the conditions required for its activity are not optimized, indicating that the overall performance of the fuel cell membrane electrode assembly (MEA) is not determined solely by the catalyst. </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> 据报道，若干研究依赖于改善重要的氧还原反应（ORR）活性以增加燃料电池的性能。然而，用于在半电池中实现优异活性的催化剂条件的应用不能保证翻译优异的性能。因此，我们研究了各种类型的市售催化剂的性能特征，包括合金催化剂，并使用线性扫描伏安法（LSV），极化曲线（IVP），循环伏安法（CV）比较了半电池和单细胞之间的趋势。）和电化学阻抗光谱（EIS）测量。此外，进行回归分析以确定用于检查半电池和单细胞性能参数之间复杂关系的影响因素。该研究表明，表达催化剂和单细胞使用孤立因子的性能是强大的挑战性。另外，即使半电池中的催化剂的测量活性高于其他半电池中的催化剂，当其活动所需的条件未得到优化时，单小区中的差异并不显着显着，表明这一点燃料电池膜电极组件（MEA）的总体性能不仅可以通过催化剂确定。</ 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6期</span><b style="margin: 0 2px;">|</b><span>共13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=Kim O.‐H.&option=202" target="_blank" rel="nofollow">Kim O.‐H.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ahn C.‐Y.&option=202" target="_blank" rel="nofollow">Ahn C.‐Y.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kang S.
