Bipolar plates are the heart of electrolysers 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 thus the measured values can be recorded and processed reliably, safely and economically in potentially explosive areas.
Our Cell Voltage Measurement Box (CVM) enables safe stack condition monitoring in hydrogen systems. It enables the differential voltage measurement of individual cells for electrolysis stacks, fuel and battery cells for data collection and analysis. It is compatible with manufacturer and fulfils all customer requirements in the hydrogen industry, including the necessary certifications.

In addition to customised contacting, customised design is also possible. The contacts are assembled on an interface board, which allows multiple contacting and, if necessary, fuse protection. The temperature-related expansion and the manufacturing tolerances of the stack must be taken into account. Compared to individual contacting, the interface solution offers significant time savings and error reduction in stack production.
The u-remote station with Ex approval for Zone 2 accepts the data collection. The data is forwarded to a gateway or a router. For connection to the control system, we provides 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 enables remote access to stationary systems. In addition to the plant operator, the stack manufacturer can also access the plant remotely for diagnostics, service and support performances. This is for preventive maintenance and to maximise the system's uptime.
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 guarantees a seamless flow of data from the stack to the cloud. This data can be used for automated machine learning (AML).
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.
