Materia Nova has a hydrogen permeation test bench that enables the evaluation of hydrogen diffusion rates and permeability coefficients through membranes, films, or sheets. The objective is to accurately measure the amount of hydrogen capable of passing through a given material in order to assess its gas barrier performance. This issue has become particularly important with the development of tanks, pipelines, seals, and polymer components intended for hydrogen applications.

The principle is based on exposing one side of a material sample to pressurized hydrogen, while the other side is maintained under controlled conditions. Hydrogen gradually diffuses through the material due to the pressure gradient. The hydrogen flux is detected by an ultra-sensitive sensor, allowing measurements of quantities in the ppm range.

The equipment enables measurements across a range of pressures (0–100 bar) and temperatures (−40 to 120 °C).

Beyond characterization, Materia Nova supports the development and optimization of high-performance barrier materials. Barrier films and coatings provide controlled permeability properties.
