Materials swap cuts cost of green hydrogen device
Coating allows titanium electrolyser components to be replaced with stainless steel
Researchers have reduced the cost of making a proton exchange membrane water electrolyser (PEMWE) by developing stainless steel-based components to replace titanium ones. PEMWEs can be used for green hydrogen production but the cost of titanium components had been limiting their commercial viability – a problem that this research could help address.
