柔性电化学电源以其柔性、形状多样性、重量轻和机械性能优异等独特优势受到越来越多的关注。在这项研究中，我们发现集流体可以显着影响大尺寸柔性电化学电源的性能。对于柔性空气自呼吸式质子交换膜燃料电池（PEMFC），只需调整集流体的方向，性能就可提高8倍以上。不同的电流收集类型的不同性能主要归因于电子转移路径的不同长度。另外，集流体的导电性对大尺寸柔性PEMFC的性能有很大的影响。采用较厚的碳纳米管膜作为集流体（低电阻）的柔性PEMFC表现出更高的性能。本文成功地建立了一个数学模型，以进一步了解其性能。此外，该模型和仿真也适用于其他柔性电源，如柔性锂离子电池和超级电容器。
Flexible electrochemical power sources are attracting increasing attentions for their unique advantages like flexibility, shape diversity, light weight and excellent mechanical properties. In this research, we discover that the current collector can dramatically affect the performance of flexible electrochemical power sources with large size. For flexible air-breathing proton exchange membrane fuel cell (PEMFC), the performance could have more than 8 times increase by only adjusting the directions of current collectors. The different performances of different current collection types are mainly attributed to the diverse lengths of the electron transfer pathways. In addition, the conductivity of current collector can dramatically affect the capability of flexible PEMFCs with large-size. The flexible PEMFCs with thicker carbon nanotube membrane as current collector (low electric resistance) show higher ability. A mathematic model is successfully built in this work to further understand the performance. Moreover, the model and simulation are also applicable to other flexible power sources, such as flexible Li-ion battery and supercapacitor.
