Distributed current and temperature measurement on membranes. Measuring the current and temperature distribution along the membrane surface visualizes flooding and drying effects, gas undersupply, compression effects on the cell, thermal hot spots and other effects. The measurements are a significant advantage in visualizing aging effects on different membrane areas and in influencing homogeneous electricity production and distribution through operational management. The characterization of bipolar plates, seals and other components provides further approaches to optimizing cell performance. Their influence on the effectiveness of the cell can be evaluated very well through comparative measurements. DILICO CURR TEMP custom thus offers a valuable insight into the interior of fuel cells, electrolyzers and redox flow batteries. Use the information to optimize the operational management and characterization of your system. Depending on the membrane area, the sensor layer, number of segments and distribution of the segments can be customized according to your requirements in order to achieve optimum monitoring of the current density and temperature distribution.
