881 Frequency Response Analyzer (FRA)
Adds EIS and HFR capability to your Scribner test system. Separates membrane resistance, charge transfer losses, and mass transport limitations in real time. HFR runs continuously during polarization testing without interrupting the experiment. Operates 1 mHz to 100 kHz (test system dependant). Integrates directly with the existing electronic load or potentiostat — no separate instrument required.
Adds a full potentiostat/galvanostat enabling hydrogen crossover by LSV, ECSA by CV, and half-cell measurements with a reference electrode — required for DOE protocols and peer-reviewed publications. Bolts directly to the 850 or mounts to the 840 / 890. Operates through FuelCell software — no separate license, data file, or computer needed.
Adds up to 16 additional data acquisition channels (voltage, temperature, current, pressure, or other analog sensor) integrated directly into the FuelCell or FlowCell software data stream. Two factory-configured eight-channel modules can be independently set for different input types. Additional sensors appear time-stamped and synchronized in the same data files as primary measurements.
The 895 is a high current relay system designed to switch various configurations of an electronic load (such as the Scribner 850), power supply, and optionally a high current EIS probe to an electrochemical cell. The 895 offers a high level of integration with the Scribner FuelCell5 electrochemical automation software. The 895 offers the following configurations for an electrochemical cell:
Load Mode: Connect the electrochemical cell directly to the test station V-Boost: Connect the electrochemical cell in series with a high current power supply to overcome iR loss in cables. Electrolysis: Connect the electrochemical cell across a power supply to perform electrolysis experiments.
This device achieves a substantial gain in automation so that you can run more kinds of experiments without needing to perform manual changeover.
Electrochemical systems are only as stable as the flows that feed them. Gas and fluid management accessories give researchers precise control over reactant delivery, flow rates, and system conditions—ensuring experiments remain consistent and reproducible.
Whether you’re optimizing reactant utilization, studying mass transport effects, or maintaining steady operating conditions, these components help create the controlled environment your experiments require.

Enables elevated anode and cathode pressure operation with integrated liquid knockout and auto draining for conditions relevant to automotive, stationary power, and pressurized electrolyzer applications up to 3 bar (45psig). Computer-controlled via FuelCell software for automated profiles, pressure cycling, and unattended operation.
Automates gas switching under FuelCell software control for ECSA measurement (N2 on cathode), hydrogen crossover, and other protocols requiring precise gas sequencing. Combined with the 885 Potentiostat: switch gases, run a diagnostic sweep, return to normal operation — all in a single software sequence without operator intervention. 3 Selectable Gases:1 Input Gas on both Anode and Cathode.
Plug-and-play accessory mounting up to 5 MFCs for integrated software-controlled gas mixing within FuelCell. Essential for contamination tolerance studies, reformate testing, oxygen concentration variation, and custom gas composition research. Internal and external configurations available.
Provides an independently controlled humid gas stream without cross-contaminating main system plumbing. Same proven sparger-based humidifier design with integrated heated gas transfer lines, automatic water fill, and all stainless steel construction. Operates independently through FuelCell software.
APPLICATIONS -Additional stream humidity control -Reformate testing with humidifier bypass -Auxiliary gas conditioning -Protocols requiring independent dew point control on multiple streams or mixed liquid and humidified gas applications
Computer-controlled back pressure regulation up to 30 bar differential with automatic draining and purge control. Engineered for two-phase flow (liquid + gas) exiting an operating electrolyzer — two-phase separation returns liquid to the test system at ambient pressure. Safety monitoring and emergency purge sequences. Compatible with third-party electrolyzer test systems.
Temperature influences nearly every aspect of electrochemical performance—from reaction kinetics to durability and efficiency. Thermal management accessories allow researchers to control, monitor, and stabilize system temperature throughout an experiment.
By maintaining precise thermal conditions, these tools enable more reliable testing, improved reproducibility, and the ability to study temperature-dependent behavior with confidence.
Heated Cuffs
Wraps cell fixture interconnect fittings — the most common cold spot between the humidifier outlet and the cell — maintaining temperature to eliminate condensation. Non-heated fittings cause gas cooling and water dropout, corrupting dew point control before gas reaches the membrane. Low power, easy to install, specifically designed for Scribner’s heated line connections.
1 or 2 channel temperature control box with integrated PID control. 115 V and 230 V options. Type T or Type K thermocouple mini connector ports. Serial connection to Scribner test systems for software control.
Constant power or temperature controlled heated lines. 115 V and 230 V options. Compatible with Scribner Temperature Control Box or as a heated line extension for Scribner Test Systems.
The Huber240 can be used instead of a normal cell heater to control the cell temperature. The Huber240 can either control its water bath temperature, or its process temperature (using a sensor in the cell).
Great electrochemical experiments start with a stable and well-designed test platform. Cell fixtures provide the physical interface between your materials and your instrumentation, ensuring consistent electrical contact, controlled reactant access, and reliable experimental setup.
Designed for flexibility and repeatability, these fixtures allow researchers to evaluate a wide range of electrodes, membranes, and cell configurations while maintaining the precision required for high-quality electrochemical data.

SOC data integrates with the 857 Flowbench and FlowCell software in the same synchronized data stream as electrochemical measurements.
The BT-110 lets you measure bare membrane strips directly — before any catalyzation — using a four-electrode technique that isolates pure ionic transport resistance and excludes contact and interfacial noise. Works in an environmental chamber or liquid bath, only potentiostat required. If you wait until after MEA fabrication to measure membrane conductivity, you can’t tell whether poor performance is the membrane’s fault or the assembly’s.
APPLICATIONS -Bare membrane ionic conductivity screening -Membrane material development and comparison -Hydration-dependent conductivity characterization -High-temperature PEM membrane evaluation (PBI, polybenzimidazole) -Quality control of incoming membrane stock -Pre-MEA material qualification
The BT-112 brings in-plane membrane conductivity measurement into your existing test system, using the hardware you already have to control temperature, humidity, gas type, and pressure around the sample. The four-electrode technique reports only ionic transport resistance — not contact resistance, not charge-transfer resistance — so the number you get is actually the membrane’s conductivity, not a composite artifact of how it was assembled. No separate environmental chamber needed.
APPLICATIONS -In-plane membrane conductivity measurement under controlled temperature and humidity -Humidity-dependent conductivity profiling -Membrane development for PEM fuel cells and electrolyzers; comparative screening of membrane materials or vendors -Pre-MEA qualification -High-temperature PEM membrane research -Academic and industrial R&D
The BT-115 is the BT-112 for use with ElectroChem hardware — same four-electrode in-plane conductivity measurement, same rigor, same ability to use your existing test system for environmental control instead of maintaining a separate chamber setup. Results are methodologically identical to BT-112 data, so cross-lab and literature comparisons hold.
