Catalyst-Layer Manufacturing

What this topic covers

Coating and assembly as sources of platinum utilization and manufacturing scrap.

Core energy-system ideas

Manufacturing determines catalyst thickness, uniformity and contact with membrane/support structures.

Platinum-bearing scrap can arise during coating, trimming and rejected-component production.

Process recipes and coating conditions are proprietary and are not provided.

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.
