新型燃料电池或推动电动航空成为现实New fuel cell could enable electric aviation
➀ 麻省理工学院研究人员开发出能量密度比锂离子电池高3倍的钠-空气燃料电池,有望推动电动航空发展;
➁ 该系统使用液态钠和空气, 产生可捕获二氧化碳的碳酸氢钠副产物,并通过分离反应物提升安全性;
➂ 初创公司Propel Aero计划将技术商业化,目标一年内推出适用于区域航空和无人机的1000瓦时/千克原型机。
➀ MIT researchers developed a sodium-air fuel cell with 3x higher energy density than lithium-ion batteries, potentially enabling electric aviation;
➁ The system uses liquid sodium and air, produces sodium bicarbonate as a carbon-capturing byproduct, and addresses safety through separated reactants;
➂ Startup Propel Aero aims to commercialize the technology for regional flights and drones, with a 1,000 Wh/kg prototype targeted within a year.
