Current Density and Temperature Distribution with DiLiCo CURR TEMP custom

DiLiCo engineering GmbH

  • Distributed and segmented measurement of current density and temperature within electrolyser, fuel cell and redox flow battery
  • Connector for distributed, segmented electrochemical impedance spectroscopy (EIS) devices
  • Visualization of operating effects such as media undersupply, flooding, drying, thermal hotspots, pressure-dependent performance
  • Measurement of locally reversible and irreversible ageing effects at the membrane
  • Ideal for analysing individual cell components such as bipolar plates (material and flow field design), seals, membrane electrode assemblies and compression concepts of the cell

Current Density and Temperature Distribution with DiLiCo CURR TEMP custom

  • DiLiCo CURR TEMP custom consists of a segmented sensor layer with integrated current and temperature sensors, electronics for evaluating the measured data, and optional software for visualization and extensive evaluation of the measured values for current density (current strength related to area) and temperature.
  • The segmented sensor layer is integrated between two cells or one cell and the end plate, without direct contact to the gases and liquids. Each segment measures the current (positive and negative) and temperature for a portion of the active area of the membrane electrode assembly flooding can be identified, directly measure and visualize the correlations between humidification systems and cell performance
  • DiLiCo CURR TEMP custom provides valuable insight into the inside of Fuel Cells, Redox-Flow-Batteries and Electrolyser to optimize operation strategies. Depending on the membrane area, the sensor layer, the number of segments and the distribution of segments can be individually adjusted according to the design of the cell.
  • The sensor layer can also be provided with a connection to create an interface for measuring electrochemical impedance spectroscopy (EIS) and to carry out parallel EIS measurements on selected segments.
  • DiLiCo engineering uses the customer design data of the cell to create a concept for integrating the sensor layer into the galvanic cell, including a dummy sensor layer for testing gas leak tightness and accuracy of position, and then manufactures the final sensor layer with the sensors.

Key features

  • Current Density and Temperature Distribution with DiLiCo CURR TEMP custom, the user has information on the condition of the cells very close to the membrane and above the membrane surface.
  • The short and long-term behaviour of the membrane is visualized with DiLiCo CURR TEMP custom. The positive and negative influences of different operating parameters and materials can be measured and allow significantly better evaluations.
  • The measurement results are used to optimize operating strategies, to detect the best material composition and increase the lifetime and efficiency of galvanic cells.
