New Porometer Designed With Manufacturers Of Fuel Cell Components In Mind
(Nanowerk News) 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, layered structure on pore structure characteristics. User-friendly and nondestructive, the Fuel Cell Porometer is an asset in quality control and R&D environments.
The Fuel Cell Porometer is designed to measure all the relevant pore structure characteristics of fuel cell components. Whether it be the pore distribution of electrodes, a change in pore size caused by humidity, or testing the surface area of through pores for testing reaction rate, the PMI Fuel Cell Porometer is built to meet the manufacturer’s needs.
The machine has the following unique measurable characteristics:
1. Characteristics measured using gas with 0 to 100 % humidity
2. Test temperatures can be 200°C and in special situations 800°C
3. Pore size measured in samples under compressive stress of up to 1000 psi
4. Pore structure of each layer of a multilayer composite
