Evolution of a GDE setup: Beyond ambient conditions

Gas diffusion electrode (GDE) setups recently and increasingly received attention as testing platforms for fuel cell catalysts. GDE provide realistic reaction conditions while remaining simple efficient to use. Therefore, bridge the gap between rotating disk (RDE) measurements membrane assembly (MEA) testing. Here, we describe our initial design development its latest improvements that allow application of high temperatures. We point out experimental challenges overcame, yet also discuss properly applying new technique avoid wrongful In particular, advocate implementing in catalyst stability investigations where so far has been used infrequently.
