摘要
随着现代电子设备向小型化、集成化方向发展,微型燃料电池作为一种高效、环保的能源转化技术,逐渐成为便携式设备的理想电源。然而,现有的微型燃料电池堆结构在电连接阻抗、体积优化和燃料分配等方面存在一定的局限性。文章提出了一种基于“扭曲带状结构”的平面式微型燃料电池堆级联结构方案,通过扭曲带状设计优化了电池单体的排列方式,实现了更高的空间集成度和更低的电连接阻抗。此外,采用共用双极板和精密微流道设计,确保了燃料的均匀分配,进一步提高了电池堆的功率输出和反应效率。文章还对该方案的技术实现、制造工艺和性能测试方法进行了详细讨论。实验表明,该设计方案在提高电池堆性能和降低制造成本方面具有显著优势,具有广阔的应用前景,尤其在便携式电子设备和物联网传感器等领域。
With the trend toward miniaturization and integration in modern electronic devices,micro-fuel cells have gradually become the ideal power source for portable devices because of their efficiency and environmental benefits.However,the existing micro-fuel cell stack structures exhibit certain limitations in terms of electrical connection impedance,volume optimization,and fuel distribution.This paper proposes a planar micro-fuel cell stack cascade structure based on a"twisted strip structure".The twisted strip design optimizes the arrangement of individual cells,achieving higher spatial integration and reduced electrical connection impedance.Additionally,the use of shared bipolar plates and precision microchannel design ensures uniform fuel distribution,further enhancing the power output and reaction efficiency of the stack.The paper also discusses in detail the technical implementation,manufacturing process,and performance testing methods for this design.Experimental results show that this design offers significant advantages in improving the performance of the stack and reducing manufacturing costs,with promising applications in portable electronic devices and Internet of Things sensors.
