Zn(Ⅱ)-Based Metal-Organic Framework/Nafion® Composite Membrane with High Proton Conductivity for Fuel Cell Applications

Kim H.-J., Kabir L., Kyungpook National University, Daegu 41566, Korea, KR

Metal-organic frameworks (MOFs) can serve as a scaffold to anchor acidic groups and provide efficient proton transfer pathways owing to their highly ordered structures and modular nature. Intentional coordination of MOFs with a conductive polymer [...]

Self-healing Composite Membranes for Fuel Cell Applications

Wang L., Advani S.G., Prasd A.K., University of Delaware, US

Defects in the form of pinholes and cracks can occur in the membrane due to a combination of chemical and mechanical degradation mechanisms during operation of the polymer electrolyte membrane fuel cell. Such defects are [...]

Tuning of Nafion® by HKUST-1 as coordination network to Enhance Proton Conductivity for Fuel Cell Applications

Kim H.-J., Talukdar K., Choi S-J, Kyungpook National University, KR

MOFs have highly ordered structures and modular nature that can serve as a scaffold to anchor acidic groups and improve efficient proton transfer pathways. HKUST-1, a MOF material containing CuII–paddle wheel type nodes and 1,3,5-benzenetricarboxylate [...]

Predicting PEMFC Pt Catalyst Durability using DFT

Groves M.N., Chan A., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

DFT calculations using B3LYP/Lanl2DZ on nitrogen doped graphene and single walled carbon nanotube structures are evaluated using Gaussian03 to measure the binding energy between its surface and a Pt atom. This is to characterize the [...]
