Electrolysis Testhousing EL25
The GFS Test Cell 25 is a highly flexible Test Housing for PEM - electrolysis, AEM -electrolysis and AEL - electrolysis. It can perform measurements with a cell size from 1 cm² to 25 cm². The housing is optimized for active material testing, high power performance and EIS-measurements. Once purchased one can easily change flowfields to test different materials and cell sizes. Futhermore the test housing can be easily expanded to a short stack or a segmented test cell for spatially resolved measurements.
Key Features:
-
Individually configurable flow field from 1 to 25 cm²
-
Designed specifically for long-term measurements and EIS testing
-
Easy gasket replacement
-
Every housing can be upgraded to a short stack
-
Available in various materials: titanium, nickel, stainless steel, and with optional coatings

Fuel Cell Test-Housing FC25
The GFS TestCell 25FC is a highly versatile test fixture for PEM fuel cell research, supporting cell sizes from 1 cm² to 25 cm². It features cartridge-based and liquid heating and is optimized for active material evaluation, high-power operation, and EIS measurements.
Flow fields can be easily interchanged to accommodate different materials, architectures, and cell sizes. The housing is modularly expandable—supporting configurations such as short stacks or segmented cells.
A wide range of gaskets in varying thicknesses is included, enabling precise adjustment of GDL and CCM compression. Liquid cooling is available as an option.
Key Features:
-
Individually configurable flow field from 1 to 25 cm²
-
Designed specifically for long-term measurements and EIS testing
-
Easy gasket replacement
-
Every housing can be upgraded to a short stack
-
Available in various materials: graphite composites, stainless steel, and with optional coatings

Electrolysis Testhousing
EL1 - Mini
The GFS TestCell EL1-Mini is a flexible Test Housing for PEM - electrolysis, AEM -electrolysis and AEL - electrolysis. It can perform measurements with a cell size from 1 cm² to 5 cm². The housing is optimized for active material testing, high power performance and EIS-measurements.
It is a compact and economic version to perform professional testing and analysis of active materials in electrolysis cells.
The cell housing comes with numerous gaskets in different heights to set different compression levels to PTLs, GDLs or electrodes.
