Platinum-Free Hydrogen Materials

Recent research is focused on cutting green hydrogen costs by replacing platinum-group metals and other expensive electrolyzer materials with cheaper alternatives.

One line of work reports durable platinum-free phosphide catalysts for anion-exchange membrane water electrolysis, while another develops corrosion-resistant stainless steel for harsh seawater and electrolyzer conditions. A separate photocatalysis study extends the same cost-reduction theme to solar hydrogen production. The shared significance is not a single finished solution, but a broader materials push toward cheaper, more scalable hydrogen production.
