The effect of non-spherical platinum nanoparticle sizes on the performance and durability of proton exchange membrane fuel cells
Tan, Xiaoyu; Shahgaldi, Samaneh; Li, Xianguo (Elsevier, 2021-11)Platinum (Pt) nanoparticles with different sizes of 2 nm and 5 nm supported on functionalized high surface area carbon (HSC) have been successfully synthesized with a one-pot synthesis technique in large scale. Of the ... -
Effect of Pt loading and catalyst type on the pore structure of porous electrodes in polymer electrolyte membrane (PEM) fuel cells
Zhao, Jian; Ozden, Adnan; Shahgaldi, Samaneh; Alaefour, Ibrahim E.; Li, Xianguo; Hamdullahpur, Feridun (Elsevier, 2018-05-01)Catalyst layer (CL) has a significant impact on the overall pore structure of the entire electrodes, thereby impacting the transport processes and the performance of polymer electrolyte membrane (PEM) fuel cells. In this ... -
A graphene-based microporous layer for proton exchange membrane fuel cells: Characterization and performance comparison
Ozden, Adnan; Shahgaldi, Samaneh; Li, Xianguo; Hamdullahpur, Feridun (Elsevier, 2018-10-01)Water management is a critical issue for proton exchange membrane (PEM) fuel cells, and the use of a microporous layer (MPL) substantially improves the PEM fuel cell performance, reliability and durability through improved ... -
A novel membrane electrode assembly design for proton exchange membrane fuel cells: Characterization and performance evaluation
Shahgaldi, Samaneh; Ozden, Adnan; Li, Xiaoguo; Hamdullahpur, Feridun (Elsevier, 2019-03-10)Conventional membrane-electrode assembly (MEA), a key component in proton exchange membrane fuel cells, only operates reasonably within a narrow range of operating conditions. In this study, a scaled-up MEA that can perform ...
