50% Pt on Nanoporous Carbon — Designed for Catalyst Durability, Not Just Initial Performance

For PEM fuel cell and electrolyzer R&D teams benchmarking catalyst lifetime under real operating and AST conditions.

Conventional high surface-area Pt/C catalysts often suffer from fast Pt degradation and carbon corrosion during operation. This Momentum Materials NCP Catalyst, built on NCP Supports™ with engineered mesopores and enhanced carbon corrosion resistance, is specifically tailored to maintain structure and performance during extended stress testing.

By optimizing Pt distribution within mesoporous networks, this catalyst delivers high performance with outstanding long-term durability, enabling accurate lifetime benchmarking for PEM systems.

Available in 1 g quantities for rapid, low-risk evaluation.

What this catalyst is not optimized for

Key features

High performance: Achieves ~1.5 A/cm² @ 0.7 V, 80% RH and ~1.2 A/cm² @ 0.7 V, 40% RH, tested at 85°C and 150 kPa.

Outstanding durability: Retains ~90% of its initial ECSA after 30,000 catalyst durability cycles and ~65% after 5,000 carbon durability cycles.

Designed for stability: Prioritizes structural integrity and Pt retention and ideal for evaluating lifetime mechanisms in PEM fuel cells and electrolyzers

Momentum Materials develops advanced carbon structures and optimizes platinum (Pt) distribution within mesoporous networks to enhance catalyst performance. Our proprietary carbon, NCP Supports™, significantly reduces Pt degradation during PEM fuel cell operation, boosting catalyst longevity. By improving Pt dispersion and tuning carbon properties, we offer high-performance and highly durable Pt catalysts tailored for industry needs. For custom Pt loadings, please contact the vendor.
