| Abstract: | Water electrolysers produce high-purity green hydrogen using renewable energy. Their efficiency and cost depend on advanced materials like porous current collectors (CCs), which distribute current uniformly across electrodes and effectively expel product gases. Traditional fabrication methods like sintering and plasma spraying are prone to surface oxidation and defects, limiting performance. This invention introduces a 3D-printed porous titanium CC with robust structure and controlled pore geometry, addressing these challenges. The novel fabrication method enables customization of pore size and design, enhancing the CC's mechanical integrity and performance in proton exchange membrane (PEM) electrolysers. Evaluations of the electrolyser stack reveal stable, high efficiency, demonstrating the suitability of this advanced CC for hydrogen production and the broader hydrogen economy. |
