Abstract:Hydrogen is potentially an ideal energy carrier, fuel and also a feedstock for various industries. However, several key challenges must be overcome for hydrogen to be used extensively in a sustainable future energy. Electrolysis, the electrolytic decomposition of water to produce hydrogen and oxygen, is very promising for green hydrogen production, yet several challenges need to be overcome. Green hydrogen can be utilized as the fuel for electricity generation by means of fuel cells. Polymer electrolyte membrane fuel cells (PEMFC) are attractive energy conversion systems for stationary, and transport applications due to their distinguishing features including high power density, low temperature operation and a compact system. Despite the enormous progress in PEMFC technology there are still core challenges for commercialization including performance, durability, and cost. In addition, we have been studying not only synthesis, production and modification of materials and components but also evaluation these materials and components in-situ in these systems for their performance and durability. We have been developing alternative polymer electrolytes, membranes, catalysts and electrodes to enhance the efficiency and performance of electrolysis and fuel cell systems.
