Electrolyzer Testing Stations
Control Software
- At the core of Leancat control systems, there is an industrial PC from Beckhoff running TwinCAT 3 runtime.
- On request, access to the TwinCAT code can be provided enabling you to modify the PLC program.
- Measured data are safely stored in an SQL database. Logging of data is optimized both to save storage space and to reduce response time when working with large data sets of time series.
Depending on you preference, you can interact with Leancat test stations in one or more of the following ways:
- Graphical user interface (GUI)
- A simplified P&I diagram is used to show process values and controls in an interactive visualization
- Users can create their own customizable dashboard with widgets such as plots, data tables or gauges for measured values
- Python scripting for the setup of automated tests
- Python is a widely used open source programming language
- Using this interface both test setup and post-processing of feasured data can be easily integrated in the testing process
- OPC UA server for high-level integration
- EtherCAT fieldbus for low-level integration
Testing Hardware
The development of electrolysers and fuel cells requires researchers to work with many degrees of freedom, whether in terms of materials used or techniques applied. Being able to quickly perform reproducible measurements is undoubtedly a great advantage.
To support these efforts, SFTec provides portfolio of tests cells of various sizes and temperature ratings. All Leancat AirCells can be quickly and easily assembled / disassembled and offer reproducibility of the compression force thanks to the air-compression mechanism.

Optimized Water Cooling
Water electrolyzers face heating challenges due to high current and ohmic losses. The optimal operational temperature for PEMWE is between 65 – 75°C.
Standard solutions use an anode water circuit for cooling, typically integrating either a plate heat exchanger for water-to-water cooling or a radiator for water-to-air cooling. Leancat water cooling method stands out particularly for compact modular systems and scenarios where waste heat cogeneration is employed.
The benefits? Reduced water volume in the anode circuit and simplified maintenance due to a compact cooling exchanger.
Innovative Compact Design:
Traditional coolers require separate pipes and fittings. Our breakthrough solution incorporates the plate heat exchanger (HEX) directly into the electrolyzer stack. This not only achieves a sleeker design but also eliminates the need to buy a separate HEX.
High-Quality Materials:
Our LCWE25 cooler, crafted from titanium and layered with an anti-corrosion coat, mirrors the construction of the electrolyzer. This ensures minimal contamination of demi-water from undesired ions.
Cost-Effective:
Combine all the above features, and the result is an electrolyzer that’s cost-effective, space-efficient, and seamlessly integrable.
