High‐speed laser drilling to scale up fuel cells and hydrogen electrolyzers: Fabricating microholes with precise geometry, superior quality, and high production rates

Scaling up clean hydrogen production using renewable energy is essential for decarbonizing a range of sectors, including transportation, chemicals, and steel, where reducing emissions and achieving net‐zero targets have proven to be challenging. Advances in laser‐based manufacturing, particularly ultra‐high‐speed laser drilling, are crucial for economically producing and scaling up hydrogen components, including high‐temperature hydrogen electrolyzers (HTHE).
