Product Overview
One catalyst chemistry, multiple substrate architectures.
Youveim® E100–E107 electrodes are engineered to help researchers change the physical electrode platform without rebuilding the entire catalyst system. The same NiFeOx concept can be supplied on stainless steel, titanium or nickel in fiber-paper, foam or woven-cloth formats.
This modular approach supports faster screening of contact resistance, electrolyte compatibility, gas release, compression behavior, flexibility and long-duration stability across alkaline electrochemical devices.
Open Gas Pathways
Porous and woven substrates provide connected channels for electrolyte access and bubble evacuation.
Format Flexibility
Select thin cloth, fiber paper or 3D foam according to cell geometry, compression and flow-field design.
System Integration
Available for coupon testing, custom cutting, MEA preparation and electrolyzer fixture matching.
Why This Platform
Designed for experimental speed and engineering relevance.
Move from basic OER screening to integrated alkaline or AEM electrolyzer evaluation using a consistent product family and comparable catalyst-loading options.
NiFeOx for Alkaline OER Research
A nickel–iron oxide catalyst layer positioned for oxygen-evolution studies and alkaline anode development.
Seven Porous Metal Platforms
Compare stainless steel, titanium and nickel across fiber paper, foam and woven-cloth structures.
Four Interface Strategies
Choose a general binder, anion-exchange ionomer, hydrophobic PTFE interface or Au-coated substrate upgrade.
From Small Coupons to Large Sheets
Standard sizes range from 1 × 1 cm to 20 × 20 cm, with non-standard cutting and processing available.
Substrate Comparison

Application Areas
Built for research cells and integrated electrolyzer workflows.
Choose a substrate architecture according to the role of the electrode in the device, not only according to catalyst chemistry.
Alkaline & AEM Water Electrolysis
Use nickel-based fiber paper, foam or cloth for anode development, catalyst-layer screening and fixture-level performance evaluation. Titanium or stainless-steel platforms can support comparative studies and specialized interface requirements.
OER Benchmarking
Compare catalyst loading, binder chemistry, substrate topology and geometric area using a consistent electrode family.
CO₂ Electrolysis Anode Support
Pair the NiFeOx oxygen-evolution electrode with a suitable cathode architecture in alkaline or anion-exchange systems.
Long-Term Interface Studies
Evaluate contact stability, substrate oxidation, compression and electrolyte exposure with optional Au-coated upgrades.

Selection Workflow
Four decisions lead to the right electrode.
Share the operating conditions together with the requested physical format to reduce iteration during quotation and engineering review.
Define the Device
Specify OER test cell, AEM electrolyzer, alkaline fixture, CO₂ electrolyzer anode or stack-level use.
Select the Substrate
Choose metal chemistry and architecture based on conductivity, corrosion, compression and gas-management needs.
Select the Interface
Choose N, A, T or G according to electrolyte chemistry, ion transport and contact-stability requirements.
Confirm the Format
Provide catalyst loading, size, quantity, cutting tolerance, active area and any MEA-processing request.
FAQ
Common product and ordering questions.
Use these answers as a starting point; final recommendations depend on the complete electrochemical and mechanical operating conditions.
What do the N, A, T and G suffixes mean?
N uses a Nafion® binder, A uses an anion-exchange ionomer, T uses a PTFE-based hydrophobic interface, and G identifies an Au-coated substrate upgrade.
Which models are most relevant to alkaline or AEM electrolysis?
Nickel-based E103, E104 and E106 are practical starting points. The A suffix is intended for anion-conducting interface matching, while the final selection should also consider cell compression, flow field and electrode thickness.
Why do Au-coated products show “Quote”?
The Au-coated configuration depends on substrate, coating specification, dimensions, quantity, masking and processing requirements, so it is confirmed on a project basis.
Can non-standard dimensions and catalyst loadings be supplied?
Yes. Provide the target size, active area, NiFeOx loading, substrate, quantity, cutting method, fixture geometry and operating conditions for review.
Are the prices shown final transaction prices?
No. They are reference prices in USD per piece. Bulk purchasing, custom processing, taxes, logistics and project-specific requirements should be confirmed before ordering.
Can the electrodes be integrated into an MEA or electrolyzer fixture?
Cutting, electrode matching, MEA-related processing and electrolyzer-fixture support can be discussed based on membrane type, active area, sealing structure and target operating conditions.
