A Link Between Design of the Fuel Cell Stack and Properties of MEAs - Experimental Evidence and its Influence on a Stack Performance Aspect (Cool-Start)

摘要

The fuel cell community has by now wholeheartedly accepted the notion of matched MEA components as necessary ingredients of fuel cell performance and durability equation. Considerable research has been conducted on optimizing the combined properties of the gas diffusion layer backing and microporous layer, catalyst and ionomer. The same logic seems to be quite universally applied to interplay between stack components and MEAs, but direct evidence as to why this would be so has not been researched or publicized widely. In this work we attempt to show such link does indeed exist, and to back up our claims with experimental data.
