Catalyst Layers in Polymer Electrolyte Membrane Fuel Cells: Formation, Characterization and Performance
(University of Waterloo, 2019-01-25)The structure of the catalyst layers (CLs) has a decisive impact on the performance, durability, and cost of polymer electrolyte membrane (PEM) fuel cells – these are the main technical challenges to the commercialization ... -
Measuring effective diffusivity in porous media with a gasket-free, radial arrangement
(Elsevier, 2019-02-01)A simple technique for measuring the effective diffusivity, and ultimately tortuosity, in porous media is presented. The method uses a custom-built apparatus, based on a radial geometry, which eliminates the need for any ...
