The 740 MTS is ideally suited for development of new ionomers and solid electrolytes. It offers rapid and accurate measurement of the through-thickness membrane resistance and conductivity as a function of temperature, humidity level and pressure.
NEW! Dr. Kevin Cooper has published a new article in the journal Macromolecules on the properties of Rigid-Rod Poly(phenylenesulfonic acid) PEMs with Cross-Linkable Biphenyl Groups for Fuel Cell Applications featuring resistance and conductivity data using Scribner’s 740 Membrane Test System (MTS). Macromolecules members can read it here: http://pubs.acs.org/articlesonrequest/AOR-Jz2HvZb8vt6gEFqXJ7B7
The 740 MTS eliminates the time-consuming approach of catalyzing a membrane and assembling a fuel cell to evaluate the ionomer performance.
*NEW* SAI now offers (2) compatible Frequency Response Analyzers for the MTS 740:
- The industry standard Solartron Analytical 1260 FRA.
- And introducing the affordable PSM1735 FRA from Newtons4th:

Download the Excel® spreadsheet that calculates the relationship between gas relative humidity, water vapor partial pressure and percent wet as function of user-defined operating conditions of humidifier temperature, sample temperature and system pressure. MTS 740 users will find this tool valuable when developing RH test profiles for membrane resistance and conductivity testing.
