Fuel Cell Development—Managing the Interfaces

Fuel Cell Development—Managing the Interfaces University of Utah,... 

The optimization of interfaces for low temperature fuel cells has always depended on the availability of specific materials to control the porosity and wetting behavioiu" of the respective pores by the electrolyte. For example, one of the breakthroughs in the development of AFCs was the work of Bacon at a time when the chemically stable hydrophobizing agent, PTFE, was not yet available [4]. Bacon managed interface control with a dual-layer, dualporosity electrode, made out of Ni powders of different grain size. The later availability of PTFE opened up new possibilities for improved GDE designs.
