Build the Cell. Run the Experiment.
Modular electrochemical cell fixtures engineered to adapt to your research—empowering fuel cell, electrolysis, and flow cell experiments.
PEM & AEM
Our gas-gas fixture offers superior performance for both Proton Exchange Membrane & Anion Exchange Membrane Fuel Cell applications, making it the ideal choice for a wide range of experimental needs.
DMFC & LIQUID/GAS
Our liquid-gas fuel cell fixture is ideal for liquid fueled cells such as Direct Methanol and Formate Fuel Cell applications. All wetted components of the liquid side are non-metallic and highly chemical resistant. Interchangeable end plates save money, convert back to PEM/AEM with one part.
RFB
Our Redox Flow Cell Test Fixture is specifically designed for use with our 857 Redox Flow Cell Test System. All non-metallic flow paths are made with non-corrosive, chemically resistant plastics only. We offer multiple assembly configurations to allow for various gap, electrode type, and thickness.
Green
Green anodized 6061-T6 aluminum without fluid ports. Use this end plate for High-Pressure Electrolysis. The green end plate is also available in a variety of materials like 316SS, Titanium, and Nickel 200 for increase resistance to operating in environments with corrosive fluids.
RED
Red anodized 6061-T6 aluminum with face mounted inlet and outlet fittings. Use this end plate for chemistries that are corrosive to aluminum like KOH. The bored through fittings provide a fully PTFE lined flow path into the flow field. The red end plate is a cost-effective solution for AEM and Liquid Alkaline Electrolysis.

BLUE
Blue anodized 6061-T6 aluminum with side mounted inlet and outlet fittings. Use this end plate for chemistries that are non-corrosive to aluminum like de-ionized water. The blue end plate is a cost-effective solution for PEM Electrolysis.
Silver
Silver customizable material (316SS, Titanium, or Nickel 200) with side mounted inlet and outlet fittings. Use this end plate for chemistries otherwise corrosive to aluminum. It is also available with face mounted fittings. The silver end plate is a robust solution for all chemistries while being easy to connect to the test system.
Serpentine
Serpentine flow channel is a continuous channel that winds back and forth across the cell. It provides uniform reactant distribution and effective water management, helping prevent flooding in fuel cells. It can, however, have high pressure drop due to the long path, increasing pumping power requirements. The serpentine pattern’s primary mass transport mechanism is diffusion. This is our most popular pattern!
Interdigitated
Interdigitated flow channel contains alternating inlet and outlet channels which force reactant gases through the porous electrode material. It enhances reactant delivery and utilization by forcing flow through the electrode and has lower overall pressure drop due to shorter path length, but can have blockages. The interdigitated pattern’s primary mass transport mechanism is convection.

Parallel
Parallel flow channel has multiple parallel channels to distribute reactants across the electrode. It has the lowest pressure drop among the designs, but it can result in non-uniform reactant distribution, leading to lower performance. It can also have less effective water management, which may cause flooding or drying of the electrode. The parallel pattern’s primary mass transport mechanism is diffusion.
custom
Have our engineers and machinists create any pattern to empower your research. We have designed Z-Parallel, Differential, Horizontal Parallel, Pocket, and other custom patterns.
Graphite is chosen for negative electrolyzer flow fields when high conductivity, corrosion resistance, and thermal stability are required. This must be balanced with the target cell voltage to avoid oxidation of the graphite. Special care should be used in handling graphite as it is a brittle material. Scribner uses an ultra-pure, densified, poco graphite that is pyro-sealed after machining creating an impenetrable part.
Platinized Titanium is primarily used on the positive (anode) side when high conductivity and corrosion resistance, under oxidizing potentials, are required. The platinized layer is applied on the active area and flag to increase electrical conductivity of the titanium and prevent the formation of titanium oxide. Can be used on the negative (cathode) side when graphite is not suitable.
316 Stainless Steel can be used as a flow field material to simulate full scale commercial systems which typically do not use exotic materials due to cost. Stainless steel will form a passive oxide layer making it suitable for mildly corrosive environments while maintaining strength. It is not as conductive as other materials but is adequately conductive and thermally stable. This material is not suitable for highly corrosive environments as it will degrade and shorten its lifespan.
Nickel 200 is highly corrosion resistant and the ultimate choice in Liquid Alkaline electrolysis for being the most inert material. It provides good electrical conductivity and is thermally stable across the range of electrolyzer operating temperatures. It is commercially available but higher cost than other materials.
Is there another material that would be better suited for your experiment? Please let us know and we can work together to create a custom solution.
This active area is roughly 2.23 x 2.23 cm and is suitable for initial scale material and process screening. This active area shares the same cell fixture hardware as the 25cm2 active area cell for easy interchangeability.
