Bipolar plates are the heart of electrolyzers used to produce hydrogen. Depending on the manufacturing process, stacks can consist of hundreds of such bipolar plates, whereby a single defective plate can negatively impact the performance of the entire stack. Because of this, it makes sense to monitor the voltage of each plate separately. We have developed the appropriate solution for this and the measured values can be recorded and processed reliably, safely, and economically in potentially explosive areas.

In addition to single connections, multiport connections are also possible. The contacts are applied to the printed circuit boards in such a way that several boards can be contacted in a single plug-in operation. The temperature-related expansion of the stack must be taken into account - for the typical stacks of PEM electrolysis, this means an enormous time savings.
Data pre-processing is handled by the u-remote station with Ex approval for zone 2. The data is passed to a gateway or a router. For connection to the control system, we provide variants for all common fieldbus protocols like PROFINET, Modbus TCP, and of course Ethernet.
In addition to the LAN connection, a connection via IoT-boxes to the customer's cloud or our own cloud is also possible. This also makes it possible to monitor the depositing of stationary equipment externally. This allows not only the user, but also the system manufacturer to access the system for diagnostics, service, or support.
With our visualization hardware and software solutions, we enable real-time data acquisition from stacks, empowering manufacturers and operators to monitor crucial parameters and identify potential failures like cell degradation, gas crossover, leaks, sealing issues, and stack contamination. Our integrated approach ensures seamless data flow from the stack to ProconWeb, where it can be fed into our on-premise or cloud-based Automated Machine Learning (AML) tool.
AML handles large-scale data, extracts valuable insights, and triggers alarm functions or email notifications on ProconWeb for anomaly detection. You can continuously improve model performance easily by retraining models as you gain more insights and collect more data from stacks and processes.
