Nerva H2Sep™ 500 alkaline electrolyser separator
A porous, nanomaterial-modified zirconia–polymer composite separator for alkaline water electrolysis. It combines low ionic resistance with high strength, usually a trade-off.
- More hydrogen per stack, or the same output at lower power
- A stronger sheet for assembly and pressure cycling
- Drop-in format: no re-tooling of frames or gaskets expected
- Domestic value addition for India's local-content requirements
