Product Overview
DiffuCarb™ E203c Pt/HSC carbon paper electrode (MGL370, AEMFC) combines a highly active platinum catalyst, high-surface-area conductive carbon, and an adaptable carbon paper substrate. It is designed for alkaline fuel cells, anion exchange membrane fuel cells, and AEM water electrolysis cathode research.
Unlike PTFE-treated hydrophobic carbon papers, E203c uses untreated MGL370 carbon paper to preserve stronger electronic conductivity and gas permeability. This configuration is especially suitable for laboratory research, short-term performance screening, and humidity-controlled operating environments.
Pt/HSC Catalyst Layer
Platinum particles supported on high-surface-area carbon provide active sites for electrochemical reactions.
MGL370 Carbon Paper
Provides mechanical support, electrical conductivity, and gas diffusion pathways for fuel cell operation.
Untreated Substrate
No PTFE treatment helps maintain higher conductivity and good gas transport under controlled humidity.
Material Composition and Structure
Electrode Performance Characteristics
High Catalytic Activity
Pt supported on high-surface-area carbon can improve electrocatalytic performance, reduce startup overpotential, and support higher overall power density.
Excellent Conductivity
MGL370 carbon paper provides strong electrical conductivity, helping reduce resistance loss and improve fuel cell efficiency.
Good Gas Diffusion
The microporous structure supports hydrogen and oxygen transport so reactants can reach the catalyst layer efficiently.
Water Management Support
The pore structure can assist water management, but operating humidity should be controlled because the substrate is not PTFE-treated.
Suitable for Alkaline Systems
The electrode can be used in AFC and AEMFC systems where alkaline environments support efficient electrochemical reactions.
AEMWE Cathode Use
It can also be used as a cathode electrode for alkaline AEM water electrolysis research.
Impact of the No-PTFE Treatment Design
| Aspect | Description | Practical Note |
|---|---|---|
| Conductivity | Untreated carbon paper retains higher conductivity because no insulating PTFE layer covers the conductive pathway. | Beneficial for high-current-density operation |
| Gas Transport | Without PTFE hydrophobic treatment, MGL370 can provide good gas diffusion under controlled humidity conditions. | Suitable for laboratory testing |
| Water Management | PTFE is commonly used to improve hydrophobicity and reduce water blockage, while untreated MGL370 requires better humidity control. | Humidity-sensitive configuration |
| Operating Environment | The no-PTFE design is more sensitive to environmental humidity and requires suitable operating conditions to maintain best performance. | Better for controlled research environments |
Application Scenarios
Alkaline Fuel Cells AFC
Can be used as an anode for hydrogen oxidation or as a cathode for oxygen reduction, providing an efficient electrochemical reaction platform.
Anion Exchange Membrane Fuel Cells AEMFC
Can improve oxygen reduction efficiency when combined with anion exchange membranes, supporting low-temperature operation and high energy efficiency.
AEM Water Electrolysis Cathode
Can be used as a cathode electrode for AEM alkaline water electrolysis research and cathode-side material evaluation.
Laboratory Research
Suitable for research environments where humidity, gas supply, and operating conditions can be carefully controlled.
Short-Term Performance Screening
Useful for catalyst, ionomer, GDL, and electrode structure comparison in controlled experimental conditions.
Electrode Structure Optimization
Suitable for studying catalyst loading, ionomer ratio, pore structure, and water management strategies.
