Surface Energy and Water Sorption Characterization of Fuel Cell Components

DVSAdventureThe research of fuel cells as alternative power generators is growing significantly. The humidity of the feed stream is vital to the performance of proton exchange membrane fuel cells. Also, the surface energies of fuel cell components is related to electro-osmotic drag, back diffusion of water, and water retention.

 

In this paper, the surface energies of different fuel cell components have been measured via Inverse Gas Chromatography (iGC SEA) over a range of relative humidities. Additionally, the water sorption isotherms have been determined using Dynamic Vapour Sorption (DVS). Learn More
