废物的回收利用是环境问题的关键参数之一。在这个问题上，超临界垃圾气化具有冲击性，有能力将垃圾转化为有市场价值的副产品。在超临界废气化炉中添加催化剂或氧化剂，可以在温和的条件下产生停留时间更短的自我维持反应，从而进一步降低运营成本。这一过程产生的氢气将被用于使用燃料电池技术发电。此外，碱性燃料电池似乎是未来的一项重要技术，因为它们可以高效率地运行。因此，超临界水生物质气化与碱性燃料电池的结合是生物质高效利用的最有潜力的应用之一。这项研究的主要目的是利用碱性燃料电池从废物中回收能量。在氢气质量分数为88.8%、二氧化碳质量分数为45%的不同操作条件下，最大功率密度为9.24W/cm2。
Recycling and utilization of waste is one of the key parameters of environmental issue. For this issue supercritical waste gasification has impactive impression, which has capability to convert the waste into marketable by-product. Adding catalysts or oxidants to supercritical waste gasifier can further reduce operating costs by creating self-sustaining reactions under mild conditions with even shorter residence times. The hydrogen produced by this process will be utilized for generating electricity using fuel cell technology. Besides, alkaline fuel cells appear to be an important technology in the future as they can operate at a high efficiency. Therefore, the combination of biomass gasification through supercritical water with alkaline fuel cells represents one of the most potential applications for highly efficient utilization of biomass. The main aim of the study is to recover energy from waste using alkaline fuel cell. With the different operation conditions 88.8 % of hydrogen and 45 % of carbon dioxide, maximum power density 9.24 W/cm2was obtained.
