单片立式气体扩散电极初探

Preliminary study on single flaky gas diffusion electrode

介绍了一种新型气体扩散电极———片状立式气体扩散电极三相界面的工作原理和优点,这种片状电极可用于气体参与反应的金属-空气电池和燃料电池。介绍了电极的制备方法,并以锌-空气单电池为例介绍了单电极的电池装置。通过实验比较了不同的聚四氟乙烯含量配方以及不同基体的单片电极在相同的实验条件下分别进行的放电性能,实验得出结论:PTFE的含量为10%和表面均匀程度高时,电池性能较好。

A new kind of gas diffusion electrode-flaky and vertical gas diffusion electrode was introduced in this paper.It can be applied to battery or fuel cell in which gas takes part in reactions.The method of making this kind of electrode was also introduced in this paper and zinc-air battery was taken as example to demonstrate the single battery set of this single electrode.Experiment was also done to compare the discharging capability of single electrode with different PTFE content and different uniformity.The results showed that the electrode with 10%(wt) PTFE and high uniformity was favorable to discharge.
