Municipal solid waste has received significant attention in advanced waste treatment engineering. A recent trend emphasizing its significance is the utilization of waste as an energy source with high efficiency and low cost. This report describes a waste-to-energy fuel cell that uses biomass, resin, plastic, and food waste directly as fuels at a temperature of 800 °C. A Fe2O3 anode demonstrated the best catalytic effect for the anode reaction among various investigated transition-metal oxides. Fe2O3 was reduced to FeO by pyrolysis gases or solid fuel at the open-circuit voltage and was then gradually reoxidized to its initial oxidation state by anodic polarization. The gasification reaction of carbon with carbon dioxide, i.e., the Boudouard reaction, was substantially catalyzed during discharge of the cell. Cell performance was dependent on the quantity and type of solid fuel: polyethylene terephthalate provided the highest power density of 0.57 W cm–2, whereas lignin presented the highest energy density of 0.83 Wh g–1 (lignin). Two distinctive features of this fuel cell are that the organic components of the solid fuels are almost completely consumed by discharge of the cell and that solid fuels can be supplied in both batch and free-fall modes.

固体氧化物燃料电池直接将城市固体废物用作燃料：生物质，树脂，塑料和食品垃圾
城市固体废物在先进的废物处理工程中受到了极大的关注。强调其重要性的最新趋势是利用废物作为高效和低成本的能源。该报告描述了一种垃圾发电燃料电池，该电池在800°C的温度下直接使用生物质，树脂，塑料和食物垃圾作为燃料。在各种研究的过渡金属氧化物中，Fe 2 O 3阳极表现出最佳的阳极反应催化作用。铁2 O 3在开路电压下通过热解气体或固体燃料将其还原为FeO，然后通过阳极极化逐渐将其还原为初始氧化态。在电池放电期间，基本上催化了碳与二氧化碳的气化反应，即Boudouard反应。电池性能取决于固体燃料的数量和类型：聚对苯二甲酸乙二醇酯的最高功率密度为0.57 W cm –2，而木质素的最高能量密度为0.83 Wh g –1（木质素）。该燃料电池的两个显着特征是，固体燃料中的有机成分几乎完全被电池放电而消耗掉了，并且固体燃料可以分批和自由降落的方式提供。
