Build the right experiment from the start – catalysts, electrolyzers, membranes, and more, cell architecture directly influences the quality of your data.
Electrochemical performance begins with the right test configuration. Whether you’re studying catalysts, developing electrolyzers, optimizing membranes, or evaluating fuel cell components, cell architecture directly influences the quality and relevance of your data.
Scribner systems support a wide range of research-grade cell fixture configurations—from simple half-cells for fundamental electrochemistry to fully integrated flow cell platforms for device-level testing.
Our flexible hardware and software architecture allows researchers to replicate real operating conditions, isolate key mechanisms, and generate reproducible data across experiments and labs.
Below are several of the most commonly used electrochemical test configurations supported by Scribner instrumentation.
Cell Configurations by Application
Fuel Cell testing
Fuel cell configurations are used to evaluate membrane electrode assemblies (MEAs) under controlled operating conditions including temperature, gas flow, humidity, and pressure. These test platforms enable measurement of key performance metrics such as polarization behavior, power density, electrochemical impedance, and durability, helping researchers analyze loss mechanisms and optimize fuel cell materials and operating strategies.
electrolyzer testing
Electrolyzer configurations support the development and characterization of water electrolysis systems, including both PEM and AEM electrolyzers. These setups allow researchers to study current–voltage performance, efficiency, impedance response, and durability while controlling operating parameters such as temperature, water feed, and pressure.
redox flow cell testing
Redox flow configurations are used to evaluate flow battery systems and circulating electrochemical reactors where electrolytes are pumped through the cell during operation. By controlling electrolyte flow rate, composition, and operating conditions, researchers can study charge–discharge performance, efficiency, transport behavior, and long-term cycling stability in scalable energy storage systems.
membrane studies
Membrane testing configurations focus on evaluating ion exchange membranes and separator materials independent of full device operation. These setups enable measurement of key properties such as ionic conductivity, resistance, permeability, and crossover, helping researchers understand membrane transport behavior and material performance for fuel cells, electrolyzers, and other electrochemical systems.

PEM/AEM Gas-Gas Fuel Cell Fixture
Standard fuel cell test fixture for gas-gas testing supporting both PEM and AEM chemistries. POCO Graphite flow fields. Available in 5, 25, and 50 cm2 active areas with serpentine, interdigitated, and differential flow field patterns. Custom flow fields and materials available.

Ultra-high purity sealed POCO graphite flow fields (serpentine and interdigitated; custom available). Gold-plated current collectors minimize ohmic resistance. Multiple configurations for varying electrode gap, type, and thickness. Modular design allows swapping flow fields and end plates for fuel cell or electrolysis applications.

These setups enable measurement of key properties such as ionic conductivity, resistance, permeability, and crossover, helping researchers understand membrane transport behavior and material performance for fuel cells, electrolyzers, and other electrochemical systems.
MTS740 Through Plane Conductivity Cell Head
Through-plane conductivity is the number that actually predicts in-device ohmic loss — it’s how ions travel during operation, across the membrane thickness, not along it. The 740 MTS Cell Head measures this directly on bare membrane samples using a patented four-terminal platinum electrode design with spring-loaded compression, so contact is consistent and results are repeatable regardless of operator. No MEA fabrication required; the 740 controls temperature, humidity, and pressure around the sample automatically.
COMPATIBLE SYSTEMS -740 Membrane Test System -Other manufacturer’s or homebuilt test systems
APPLICATIONS -Assess ion transport across membrane thickness — directly predicts in-device ohmic loss -Use with impedance analyzer like the Solartron 1260, N4L PSM 1735, or an Ivium Potentiostat with EIS
In-plane and through-plane conductivity are not the same number, and for anisotropic membranes — like reinforced GORE membranes — the difference tells you something important about microstructure. The BT-710 swaps into the 740 MTS in place of the standard cell head, giving you in-plane measurements under the same precise, software-controlled temperature and RH protocols instead of relying on a static environmental chamber. Pair it with the standard cell head and you have the complete picture.
