Product Overview

A configurable porous-electrode platform

One catalyst and one conductive scaffold can produce distinctly different electrode interfaces when the binder chemistry is changed. The E100 Series is designed around this principle, enabling researchers to compare protonic, anionic, and hydrophobic catalyst-layer configurations on a common metal-fiber substrate.

Designed to connect catalyst chemistry with practical electrode engineering

The interconnected stainless-steel fibers form a continuous electronic pathway while also supporting catalyst deposition across a highly accessible porous surface. This architecture helps distribute the catalyst layer through a three-dimensional conductive framework instead of limiting the active material to a dense planar support.

Binder selection is used as an interface-control tool. It affects particle cohesion, adhesion to the metallic substrate, local ion accessibility, liquid wetting, bubble release, and the balance between flooded and gas-accessible pore regions. E100N, E100A, and E100T therefore share the same base catalyst–substrate concept but are optimized for different research questions.

Continuous metallic conduction through an interconnected fiber network
Large accessible surface for catalyst deposition and electrochemical contact
Binder-defined interface options for different electrolyte and membrane studies
Porous pathways that support electrolyte penetration and gas disengagement
Suitable for catalyst screening, electrode optimization, and durability studies

Standard preparation route

Spray-coated catalyst layer

NiFeO_x catalyst and the selected binder are formulated into an ink and deposited onto porous stainless-steel fiber paper. The process is intended to create a distributed catalyst layer while preserving the open structure of the metallic scaffold.

Electrode Architecture

Three functional layers working together

The E100 architecture combines catalyst activity, binder-controlled microstructure, and a porous metallic support. Each component serves a different role, and overall electrode behavior depends on their interaction.

NiFeO_x catalytic phase Provides active sites for alkaline oxygen-evolution studies.

Binder-controlled interface Tunes adhesion, ion-contact behavior, wetting, and pore accessibility.

Stainless-steel fiber-paper scaffold Supports electron transport, mechanical integrity, and gas–liquid pathways.

A Electronic transport

The continuous stainless-steel fiber network acts as a current-collecting framework and reduces the need for electron transfer across isolated particles or poorly connected planar regions.

B Ionic contact

The binder influences how electrolyte or membrane-side ions reach the catalyst layer. An anion-conducting binder is generally more aligned with alkaline and AEM interface studies, while Nafion enables a different reference interface.

C Wetting and bubble release

Hydrophilic and hydrophobic balance can affect electrolyte filling, bubble detachment, and transport resistance. The PTFE version is intended for studies where reduced flooding or improved gas release is important.

D Mechanical support

The fibrous metallic substrate provides a flexible yet structurally coherent support for catalyst deposition and repeated electrochemical assembly.

Model Details

Binder-specific electrode variants

Each model is built around a distinct interface strategy. The descriptions below clarify the intended role of each configuration without implying universal compatibility with every membrane or electrolyte.

E100N

NiFeO_x / stainless-steel fiber paper / Nafion binder

Reference ionic interface

E100N uses Nafion as the catalyst-layer binder. It is designed to provide strong particle cohesion and a continuous ionomer-containing interface, making it useful as a reference electrode for studies comparing binder chemistry, catalyst-layer adhesion, and local ionic contact.

Nafion-based catalyst-layer formulation
Supports cohesive catalyst deposition on the metal-fiber scaffold
Useful for controlled comparison against anion-conducting and PTFE systems
Actual chemical stability must be verified under the intended alkaline conditions

E100A

NiFeO_x / stainless-steel fiber paper / anion-exchange resin

Alkaline / AEM

E100A uses an anion-exchange resin binder to create a catalyst layer better aligned with alkaline ion transport and AEM-type interfaces. It is the primary E100 configuration for alkaline oxygen-evolution and AEM water-electrolysis research.

E100T

NiFeO_x / stainless-steel fiber paper / PTFE binder

Hydrophobic transport

E100T incorporates PTFE to introduce hydrophobic character into the catalyst layer. The configuration is intended to reduce excessive liquid accumulation in selected pore regions and to support oxygen-bubble release during gas-evolving operation.

PTFE-based catalyst-layer structure
More hydrophobic interface than the ionomer-bound variants
Useful for studying flooding, bubble removal, and pore accessibility
Suitable for transport-focused and extended-operation experiments

Selection Guide

Choose the model by interface requirement

Start with the electrochemical environment, then identify the required ion pathway and wetting behavior. Substrate-surface requirements should be considered after the catalyst-layer interface has been defined.

Step 1

Identify the electrolyte and membrane

Determine whether the test is alkaline liquid-electrolyte, AEM-based, or an interface-comparison experiment.

Step 2

Select the ion-interface strategy

Use E100A for anion-conducting research or E100N as a Nafion-containing reference configuration.

Step 3

Evaluate wetting and gas release

Use E100T when flooding control, hydrophobicity, or oxygen-bubble release is a primary research variable.

Step 4

Check substrate-interface needs

Consider E100G when surface oxidation, contact resistance, or corrosion-sensitive comparison is important.

Recommended starting model for alkaline AEM anode research

E100A is generally the most directly aligned option when an anion-conducting catalyst layer is required.

Frequently Asked Questions

Technical selection questions

These answers clarify the intended use of each configuration and highlight the validation steps required before long-duration operation.

Which model is most suitable for AEM water electrolysis? +

E100A is the preferred starting configuration because it uses an anion-exchange resin binder. Final selection should still consider the exact membrane chemistry, electrolyte concentration, temperature, compression, and required durability.

Is E100N a PEM-electrolysis anode? +

No universal PEM compatibility is implied. E100N identifies a Nafion-bound NiFeO_x electrode and is mainly useful for binder-interface or comparative research. NiFeO_x and the stainless-steel substrate must be evaluated carefully under acidic PEM conditions.

When should E100T be selected? +

Select E100T when hydrophobicity, water management, bubble release, or flooding resistance is a major experimental variable. PTFE improves hydrophobic character but does not provide the same ionic pathway as an ion-conducting binder.

What is the main purpose of the E100G option? +

E100G is intended for studies that require a more stable and conductive substrate surface. Gold coating can reduce the influence of stainless-steel surface oxidation and improve electrical contact consistency, although full system compatibility must still be verified.

Can electrode size and catalyst loading be customized? +

Yes. Electrode dimensions, catalyst loading, binder family, and substrate configuration can be discussed according to the active area, fixture design, operating current, and target test protocol.
