In our group membrane based elctrolyzers are developed for the production of H₂ using novel processes like the hybrid sulphur (HyS) process where the hydrogen is produced by the oxidation of SO₂ in the presence of water forming H₂SO₄.  Both new and existing membranes are screened for their suitability for this process in terms of proton conductivity, SO₂permeance and H₂SO₄ stability.Screen printer F1-12 from Systematic Automation
