摘要

Abstract > The durability of high‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs) was studied with phosphoric acid doped membranes of polybenzimidazole (PBI). One of the challenges for this technology is the loss and instability of phosphoric acid resulting in performance degradation after long‐term operation. The effect of the gas diffusion layers (GDL) on acid loss was studied. Four different commercially available GDLs were subjected to passive ex situ acid uptake by capillary forces and the acid distribution mapped over the cross‐section. Materials with an apparent fine structure made from carbon black took up much more acid than materials with a more coarse apparent structure made from graphitized carbon. The same trend was evident from thermally accelerated fuel cell tests at 180?°C under constant load where degradation rates depended strongly on the choice of GDL material, especially on the cathode side. Acid was collected from the fuel cell exhaust at rates clearly correlated to the fuel cell degradation rates, but amounted to less than 6% of the total acid content in the cell even after significant degradation. Long‐term durability of more than 5,500 h with a degradation rate of 12 μV h ?1 at 180?°C and 200 mA cm ?2 was demonstrated with the GDL that retained acid most efficiently. </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 XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <标题类型=“main”>抽象</ title> > 研究了高温聚合物电解质膜燃料电池（HT-PEMFC）的耐久性，用聚苯和咪唑（PBI）磷酸掺杂膜。这种技术的挑战之一是磷酸的损失和不稳定性导致长期操作后的性能降解。研究了气体扩散层（GDL）对酸损失的影响。四种不同的商业上可获得的GDL被动 ex situ </ i> 通过毛细力和酸分布在横截面上进行酸的吸收。具有由炭黑制成的表观精细结构的材料比具有更粗糙的石墨碳制成的粗糙结构的酸多得多。在恒定载荷下在180°C下的热加速燃料电池试验中可以明显是相同的趋势，其中劣化速率在基于GDL材料的选择上依赖，特别是在阴极侧。从与燃料电池降解速率明显相关的速率从燃料电池排气中收集酸，甚至在显着降解后，甚至在细胞中总酸含量的少于6％。长期耐久性超过5,500小时，降解速率为12μVH ？1 </ sup> 在180？°C和200 ma cm ？2 </ sup> 用最有效地保留酸的GDL证明了。 </ 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>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共10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=Kannan A.&option=202" target="_blank" rel="nofollow">Kannan A.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Li Q.&option=202" target="_blank" rel="nofollow">Li Q.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Cleemann L.
