微流体燃料电池的流道集合了传统燃料电池的核心部件(电极、集流板、质子交换膜)及功能(燃料的传输、生成物的转运),由此可见微流体电池的结构形式对其性能的重要性,而受结构影响较大的耗尽边界层及反应液交界面扩散层厚度很大程度上制约了微流体燃料电池性能的提升。介绍了几种控制耗尽边界层及反应液交界面扩散层的微流体燃料电池结构,并说明了这些结构在解决问题的同时所带来的"副作用",为微流体燃料电池结构设计提供一定的参考。
The core parts of traditional fuel cell such as electrodes, current collector plates and proton exchange membrane with its functions such as fuel delivery and resultant removal are all congregated to the microfluidic channel in a microfluidic fuel cell, so the structure of microfluidic channel is very important for the performance. The performance of microfluidic fuel cell is mostly affected by the thickness of depletion boundary and inter-diffusive layers affected by cell architecture design. Several methods to control the depletion boundary and inter-diffusive layers were summarized, and the side effects of these methods were summarized, aiming to provide some reference for further microftuidic cell fuel architecture design.
