杂草废弃物是一种丰富的碳中性能源回收原料。提高废物转化为能源效率的一种潜在方法是在处理系统中应用燃料电池型反应堆，以高功率和高能量密度的原料发电。在此，我们报告了一种固体氧化物燃料电池（SOFC），直接使用固体杂草废料作为燃料。本研究以芒草、加拿大一枝黄花和蒙大拿州葛根为研究对象。这些草的转化反应，特别是原位气化，在800℃下通过沉积在阳极衬底上的薄层银-铁（III）氧化物混合物有效地催化。加拿大一枝黄花和蒙葛根的功率密度最高，分别为0.41 W cm（-2）和0.42 Wh g(-1)，其功率密度与其木质素和灰分含量密切相关。重要的是，该SOFC不仅在批量模式下表现良好，而且在连续自由落体模式下也表现良好。(C) 2021作者。Elsevier Ltd.出版。
Weed waste is an abundant and carbon-neutral feedstock for energy recovery. A potential approach to improve the efficiency of waste-to-energy conversion is the application of a fuel-cell-type reactor to the treatment system to generate electricity from the feedstock, with high power and energy density. Herein, we report a solid oxide fuel cell (SOFC) that directly uses solid weed waste as fuel. Grasses tested in this study were Miscanthus sinensis, Solidago canadensis, and Pueraria montana. The conversion reactions for these grasses, especially in situ gasification, were effectively catalyzed at 800 degrees C by a thin layer of a silver-iron(III) oxide mixture that was deposited onto the anode substrate. The use of Solidago canadensis and Pueraria montana provided the highest power density (0.41 W cm(-2)) and energy density (0.42 Wh g(-1)), respectively, which were closely related to their lignin and ash contents. Importantly, this SOFC exhibited good performance not only in batch mode but also in continuous free-fall mode. (C) 2021 The Author(s). Published by Elsevier Ltd.
