The PMI Fuel Cell Porometer provides fully automated through-pore analysis including pore-throat diameter, pore size distribution, mean flow pore diameter, and liquid & gas permeability. The porometer’s versatility allows the user to simulate operating conditions. The instrument has special features to measure the effects of compressive stress on a sample, test temperature, sample orientation, and layered structure on pore structure characteristics. The fully automated, user-friendly Fuel Cell Porometer is an asset in quality control and R&D environments.
Measured flow rates through dry and wet samples with increasing differential pressure are used to compute many characteristics.
- Pore throat diameters
- The largest pore throat diameter
- Mean flow pore diameter
- Pore distribution
- Gas permeability
- Through pore surface area (Envelope Surface Area)
