Abstract
With increasing research into hydrogen-fueled commercial aviation, polymer-based materials are being explored for use in lightweight liquid hydrogen storage tanks. This thesis investigates the adaptation of the Devanathan-Stachurski (DS) cell, traditionally used for studying hydrogen permeation in metals, as a testing method for polymeric materials. Unlike conventional high-pressure techniques, the DS cell offers a compact, efficient, and safer approach by using electrochemistry to evolve hydrogen in minute quantities. This adaptation has the potential to assess permeability, diffusivity, and solubility of polymer-based materials while avoiding the complications associated with high-pressure hydrogen techniques.
