740 Membrane Test System

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. The 740 MTS eliminates the time-consuming approach of catalyzing a membrane and assembling a fuel cell to evaluate the ionomer performance.
