摘要

采用激光穿孔法制备了超薄多孔传输层（PTL）。所采用的钛箔厚度为25 ~ 127 μm。在基于激光的工艺中，创建了具有控制和规则图案的多孔传输层。该工艺涉及烧蚀加工表面结构以及尺寸从10到100 μm的通平面孔。多孔输运层被设计成具有微米尺寸通道的高度有序模式，这显著提高了它们的质量输运性能。激光穿孔钛箔通过降低电池电阻，在聚合物电解质膜电解中表现出优异的性能。激光穿孔钛箔与标准PTL的结合使其高频电阻（HFR）低于标准PTL。

Application of Laser-Perforated Titanium Foils in Polymer Electrolyte Membrane Water Electrolysis

Ultrathin porous transport layers (PTL) were prepared by laser-perforation of titanium foils. The thickness of employed titanium foils ranged from 25 to 127 μm. In the laser-based process, porous transport layers with controlled and regular patterns were created. The process involved the ablative fabrication of surface structures along with through-plane holes ranging from 10 to 100 μm in size. The porous transport layers were designed with highly ordered patterns featuring micron-sized channels, which enhance their mass transport properties significantly. Laser-perforated titanium foils showed remarkable performance in polymer electrolyte membrane water electrolysis by lowering the cell resistance. The combination of laser-perforated titanium foil and standard PTL resulted in lower high-frequency resistance (HFR) compared to the standard PTL.
