Membranes & Platinum Catalyst Performance

What this topic covers

Why membrane properties influence the environment around platinum catalysts.

Core energy-system ideas

PEM membranes conduct protons while separating reactant gases.

Membrane hydration, durability and crossover affect catalyst-layer operation.

Membrane and catalyst improvements are interdependent at MEA level.

Important tradeoffs

Catalyst-layer performance emerges from reaction kinetics and transport at the same time.

Material and performance evidence

Lower platinum loading can increase sensitivity to local transport or degradation effects.

Lifecycle perspective

Manufacturing scrap is part of platinum material accounting and can be an important recycling stream.
