Group 1 - The research team from the University of Leicester has developed an efficient method using acoustic technology to separate materials, enabling effective recovery of fuel cells and extraction of precious metals while preventing harmful chemicals from entering the environment, thus providing a new pathway for sustainable development in clean energy [1] - Fuel cells and electrolyzers are crucial components of hydrogen energy systems, widely used in transportation such as cars, trains, and buses, with catalyst-coated membranes (CCM) containing expensive platinum group metals and fluoropolymer membranes (PFAS) that are difficult to degrade and can contaminate drinking water if not handled properly [1] - Traditional recycling methods struggle to efficiently separate PFAS membranes from CCM due to their strong adhesion, limiting the circular use of fuel cells, prompting researchers to propose an innovative recovery strategy involving organic solvent soaking followed by water ultrasonic treatment to effectively detach PFAS membranes from precious metals [1] Group 2 - The research team has further developed a continuous layered process using a custom blade-type ultrasonic generator that creates tiny bubbles under high-frequency ultrasound, which can release precious catalysts from materials within seconds at room temperature, making the process energy-efficient and environmentally friendly [2] - This innovation not only enhances recovery efficiency but also lays the foundation for large-scale industrial applications, with the potential to be utilized in the hydrogen energy industry for sustainable resource management and environmentally friendly processing, contributing to the establishment of a truly green energy system [2]

这项创新不仅提升了回收效率,也为大规模工业化应用奠定了基础。未来,该技术有望用于氢能产业, 实现资源的可持续管理和环保处理,构建真正的绿色能源体系。 (文章来源:科技日报) 由于PFAS膜与CCM之间黏附力极强,传统回收方法难以将其高效分离,限制了燃料电池的循环利用。 为此,研究人员提出了一种创新性回收策略:先用有机溶剂浸泡材料,再结合水超声处理,成功实现了 PFAS膜与贵金属的有效剥离。 这一方法操作简便、可扩展性强,无需使用强腐蚀性化学品,大幅降低了环境污染风险。研究人员认 为,这将彻底改变燃料电池的回收方式,推动铂族金属循环利用,从而降低清洁能源技术的成本。 在此基础上,研究团队进一步开发了一种连续分层工艺,采用定制刀片式超声波发生器,在高频超声作 用下产生微小气泡。这些气泡在高压下破裂,可在几秒钟内将珍贵的催化剂从材料中释放出来,整个过 程在常温下完成,节能环保。 英国莱斯特大学研究团队开发出一种利用声波技术高效分离材料的新方法,不仅能有效回收燃料电池, 分离其中的贵金属等关键资源,还能防止有害化学物质进入环境,为清洁能源的可持续发展提供了新路 径。 燃料电池和水电解槽是氢能系统的重要组成部分,广泛应 ...
