Proposals should address the following:

• Develop a generic open-access monitoring and diagnostic platform that enables interoperability and thus allow for its utilisation by different electrolyser technologies;
• Identify suitable cell, stack and system level monitoring parameters which indicate a possible critical state of the cell/stack/module within the system;
• Develop reliable diagnostic algorithms to determine the remaining useful lifetime depending on the state of health of the cell components/cell/stack/module. Both physical model-based approaches and data-driven approaches are eligible;
• Develop the hardware for the implementation of these advanced Monitoring, Diagnostic and Lifetime Prediction tools that is able to interact with common control units and power electronics of the electrolyser system to trigger counter actions;
• Validate the diagnostic approach and the developed hardware for monitoring and lifetime prediction on at least two technologies (PEMEL, AEL, AEMEL or SOEL) in laboratory scale;
• Develop and propose strategies to sustain performance and improve durability of cells, stacks and systems for each tested technology. Demonstrate the effectiveness of the proposed strategy on short stack level or larger;
• Demonstrate functionality and resilience of the devices on electrolysers of power > 100 kW operated in representative or real conditions on at least one technology (PEM, AEL or SOEL), including fluctuating RES electricity input. Any demonstrator used in the proof-of-concept phase should already exist or be funded by other projects (TRL 6);
• Provide the prospect to integrate the tool for real time simultaneous monitoring of multiple stack and module key parameters and indicators. The EMS will receive output data in real-time from physical/virtual sensors of the EMS;

Proposals may address the following:

• Establish database of the measured experimental data to help future efforts into the development of new electrolyser operation schemes.
• Ensure the efficiency of the monitoring system in all kinds of environments.
