International stack makers

A separator that outperforms the premium benchmark

Stack makers in Europe, the Middle East and beyond compete on efficiency and durability. Nerva H2Sep 500 delivers more current than a premium composite reference in the same cell, in a much stronger sheet.

The challenge

What international stack makers need

The efficiency race

Higher current density at the same voltage is the clearest route to lower-cost hydrogen.

Qualification burden

Switching suppliers needs reproducible data at the customer's operating conditions.

Durable gas separation

Low-cost fabric diaphragms trade gas purity for conductivity; composite separators are needed for advanced, pressurised stacks.

How Greenprastha helps
