讲座内容：

Anion exchange membrane water electrolyzers (AEMWEs) hold great potential to overcome many of the performance and cost limitations of incumbent water electrolysis technologies. However, they still face significant challenges related to efficiency and durability. Impeded bubble release and limited electron conduction processes represent major bottlenecks for the large-scale application of AEMWEs. The bubble dynamics behavior and continuous electron transfer can be effectively improved using electrodes in porous structure. Herein, for concept proof, a TPMS-G porous electrode was designed and fabricated using 3D printing, followed integration of a homemade Fe-doped Raney Ni catalyst, deposited via a collaborative atmospheric plasma spraying (APS) process. This hybrid additive manufacturing is capable to develop a multi-scale porous electrode, facilitate bubble discharge and electrolyte penetration. And simultaneously, the Fe-doped Raney Ni catalyst provides more efficient active sites, which results in superior HER and OER performance. This work provides valuable insights into the development of innovative porous electrodes for industrial water electrolyzer via additive manufacturing.
