PEM Fuel-Cell Applications
Vehicles, backup systems, material handling and stationary power as different duty cycles.
What this topic covers
Vehicles, backup systems, material handling and stationary power as different duty cycles.
Core energy-system ideas
Different applications emphasize power density, start-up behavior, lifetime, cost or serviceability.
Platinum requirements therefore vary with system architecture and duty cycle.
Comparing technologies requires matching the same end-use requirement.
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.
