Hydrogen electrolysis: Laser drilling <\/strong><\/mark>of titanium electrodes<\/h2>\n\n\n\n

Hydrogen is a key energy source of the future. Electrolysis uses electricity to split water into hydrogen (H\u2082) and oxygen (O\u2082). The most important processes are PEM and alkaline electrolysis.<\/strong><\/p>\n\n\n\n

PEM <\/strong>(proton exchange membrane) electrolysis <\/strong>uses an acidic electrolyte that is highly efficient but corrosive. Alkaline electrolysis works with a basic solvent and is more cost-effective. Due to the aggressive conditions, titanium components are often used in PEM systems to increase the durability and lifetime of the components.<\/p>\n\n\n\n

Titanium is ideal for laser processing with ultrashort pulse lasers, especially for high-precision drilling, cutting, or structuring processes<\/strong>. Due to their high complexity and technical requirements, the titanium components to be processed are often produced using 3D printing and then further machined using a subsequent laser processing<\/strong> step.<\/p>\n\n\n\n
