Fuel-Cell Stack Design Context
How many cells, plates, manifolds and balance-of-plant components surround the platinum-containing MEAs.
What this topic covers
How many cells, plates, manifolds and balance-of-plant components surround the platinum-containing MEAs.
Core energy-system ideas
A stack connects many electrochemical cells electrically and hydraulically.
Platinum is concentrated in the catalyst layers, not spread uniformly through the whole stack.
System cost and reliability also depend on plates, seals, compressors, pumps, controls and thermal management.
Important tradeoffs
Catalyst loading should be evaluated together with mass activity, transport, manufacturing and durability.
Material and performance evidence
Water, heat, gas purity and transient operation can change how effectively platinum catalyst layers perform.
Lifecycle perspective
The stack contains much more than platinum, so catalyst improvement does not eliminate balance-of-plant constraints.
