Optimized Design of the MEMS Micro-Fuel Cell System Structure
With the trend toward miniaturization and integration in modern electronic devices, micro fuel cells have gradually become the ideal power source for portable devices due to 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 IoT sensors.
