Thermal Management & Catalyst Durability

What this topic covers

How temperature distribution affects membrane, catalyst and stack life.

Core energy-system ideas

Fuel-cell reactions generate heat as well as electricity.

Uneven temperature can change water balance and accelerate degradation.

Cooling-system procedures and settings are outside this site's scope.

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.
