Product Overview
A practical NiFeOx electrode family for interface-focused electrochemical research
The Youveim® E105 Series uses nickel–iron oxide as the active electrocatalytic material and high-purity stainless-steel cloth as the porous conductive framework. The woven metallic structure provides mechanical support, electrical pathways, and open channels for electrolyte penetration and gas release.
A controlled spray-coating process distributes the NiFeOx catalyst layer across the stainless-steel cloth. This approach supports uniform surface coverage while allowing the catalyst loading and interfacial formulation to be adjusted for different experimental requirements.
The model family is organized around the binder and surface interface. E105N uses Nafion, E105A uses an anion-conducting resin, E105T uses PTFE to create a more hydrophobic interface, and E105G introduces Au surface modification for enhanced corrosion protection and long-duration operation.
The series is primarily positioned for alkaline and neutral electrochemical research. Compatibility with acidic media depends on electrolyte composition, potential window, exposure time, substrate grade, and the exact electrode configuration, and should therefore be confirmed before use.
Adjustable catalyst loading
Standard loading can be tailored within the specified 1–10 mg/cm² range.
Application-specific binders
Nafion, anion-conducting resin, and PTFE create distinct ionic and wetting environments.
Research-oriented customization
Alternative ionomer systems can be discussed for specialized catalyst-layer studies.

Binder System Logic
The binder defines more than mechanical adhesion
Binder chemistry affects local ionic pathways, electrolyte wetting, catalyst utilization, bubble detachment, and integration into a membrane-electrode or flow-cell environment.
Customized ionomer systems such as Fumion®, PiperION®, or
NEXIONIC® may be discussed for specialized research. Availability,
solvent compatibility, binder concentration, and processing
conditions should be confirmed before production.
Nafion Provides an ionomer-assisted, wettable catalyst layer and a practical reference configuration.
Anion resin Supports an alkaline ionic environment for AEM and hydroxide-transport studies.
PTFE Adds hydrophobic character for gas release and gas–liquid interface control.

Document loading, active area, electrolyte, temperature, pretreatment, flow, reference system, and polarization protocol.
Research-use notice:
Electrochemical performance depends on catalyst loading, exposed
area, electrolyte chemistry, temperature, cell geometry,
compression, flow, counter electrode, reference system, and test
protocol. The listed current-density range is a product-reference
value rather than a guaranteed cell-performance result.
