These customers already trust DiLiCo cell voltage measurement technology:


DiLiCo cell voltage 48/96 measures fast and reliable the electrical voltage of each individual cell on fuel cells, batteries and during electrolysis. Furthermore, it additionally monitors the adjustable limits for undervoltage and overvoltage. The integrated floating contact can be used for customer-side control to protect the cell(s)from damage and the plant from failure when voltage limits are reached. The measurement interval of DiLiCo cell voltage 48/96 is up to 20 ms for 48 cells and for example up to 30 ms for 240 cells. The modules can be linked via a BUS system through the CAN interface to measure the cell voltages of stacks with more than 96 cells.

By DiLiCo cell voltage 48/96, you have the minimum load on the electrodes due to the low current consumption of ± 2 µA when measuring cell voltage. No energy drain when used on batteries. DiLiCo cell voltage 48/96 is suitable for all common energy converters and storage devices for cell voltages up to 4.5 V per cell. The measurement data is transmitted to the controller via an RS232 or CAN interface


DiLiCo cell voltage 48/96 features an external power supply (15 - 36 VDC) and a 50-pin D-sub female connector for connecting cell voltage taps. Use DiLiCo cell voltage 48/96 to detect faults and adverse operating conditions in a timely manner, avoiding failure and maintenance costs and increasing cell life. Ensure customer satisfaction by detecting faults in a timely manner and preventing cell failure.

Why it makes sense to measure cell voltages in a fuel cell?

  • By a continuous cell voltage monitoring, the failure of a cell and thus also the failure of the system can be avoided.
  • The measurement of the cell voltage in continuous operation is cheaper than the time-consuming search for a defective cell and the costly maintenance.
  • The use of cell voltage monitoring can ensure the quality assurance of the cells during operation and identify systematic errors in cells.
  • Collected information by measuring cell voltages can be used to optimize operations management or the next generation of stacks.
