Abstract
Green hydrogen produced by water electrolysis is one of the most promising technologies to realize the most effective way of utilizing intermittent renewable energy globally. Among the various electrolysis technologies, the emerging Anion-Exchange Membrane Water Electrolysis (AEMWE) shows promising potential for producing green hydrogen at a competitive price.
The low ion conductivity of the Anion Exchange Membrane (AEM) is found to be one of the major limitations of AEMWE. In this thesis, the AEM is aligned while casting using an alternating current electric field to improve the ion conductivity of AEMs. The stability of the electrically aligned membrane is tested using various characterisation techniques. The electrically aligned membranes showed a 300% increase in ion conductivity, with a slight decrease in mechanical stability.
