Water Electrolyzer Stacks LCWE 25-HEX
Key features
- Advanced PEM water electrolyzer stack
- Produces hydrogen at high pressure (cathode)
- Low-pressure oxygen outlet (anode)
- Designed for integration in H2 systems
- Power range up to 5 kW
- Integrated heat exchanger for stack cooling (optional)
Applications
With its high power density, efficiency and reliability, LCWE-25 is perfectly suited for OEMs and integrators aiming at developing their own solution for the production of green hydrogen.
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. Our 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.
