摘要
质子交换膜燃料电池是一种将存在于燃料与氧化剂中的化学能直接转化为电能的发电装置,双极板作为燃料电池的关键部件,3D打印技术可以适应双极板加工的需要。设计了一种具有并联传动机构的3D打印系统,采用聚乳酸(PLA)塑料作为加工材料,通过对3D打印系统控制参数的设置和优化,保证了加工零件的精度,完成了具有平行流道和蛇形流道的双极板的制造。燃料电池的组装实验证明,采用3D打印加工的燃料电池具有与传统加工方法获得的燃料电池相似的良好的工作性能。
Proton exchange membrane fuel cells （PEMFCs） are electricity generation devices by which the chemical energy of the fuel and oxidant directly converts into electricity. 3 D printing technology is suitable to fabricate PEMFCs bipolar plates, one of important components in PEMFCs. The paper designed a kind of 3D printing apparatus with parallel transmission mechanism. The apparatus adopted polylactic acid （PLA） as manufacturing material, and ensured the machining accuracy through setting and optimizing controlling parameters. The experimental results testify that fuel cells made by 3D printing have pretty good performance similar to the fuel cells obtained from traditional manufacturing methods.
