Ultrathin electrolyzer coatings cut platinum use and hydrogen cost

Researchers proposed ultrathin coatings for corrosion-resistant components of PEM water electrolyzers. The approach aims to reduce platinum consumption and lower the cost of climate-friendly hydrogen production for industry.

• PEM electrolysis needs components that withstand highly corrosive conditions
• Some of these parts are currently coated with platinum
• Ultrathin coatings reduce use of the expensive metal
• Goal is cheaper climate-friendly hydrogen production
