Investigating Phase-Change-Induced Flow in Gas Diffusion Layers in Fuel Cells with X-ray Computed Tomography
(Journal article; Peer reviewed, 2017)The performance of polymer‐electrolyte fuel cells is heavily dependent on proper management of liquid water. One particular reason is that liquid water can collect in the gas diffusion layers (GDLs) blocking the reactant ... -
Method for studying high temperature aqueous electrochemical systems: Methanol and glycerol oxidation
(Journal article; Peer reviewed, 2016)A method for high purity aqueous electrochemical experiments at temperatures above the normal boiling point of water and at temperatures up to 140 °C is described. A three-electrode cell in a self-pressurized glass autoclave ... -
Ni/NiO nanosheets for alkaline hydrogen evolution reaction: In situ electrochemical-Raman study
(Journal article; Peer reviewed, 2020)Nickel/Nickel oxide (Ni/NiO) nanosheets heterostructure is a cheap and active catalyst for hydrogen evolution reaction (HER) in alkaline electrolytes. However, the reason for this activity is still under debate. Herein ... -
NiCu mixed metal oxide catalyst for alkaline hydrogen evolution in anion exchange membrane water electrolysis
(Peer reviewed; Journal article, 2021)We report on the optimization of nickel-copper catalysts for superior performance as a cathode catalyst in anion exchange membrane (AEM) water electrolysis. The bifunctional system of NiCu mixed metal oxide (MMO) nanosheets ... -
Reversible heat effects of lithium metal- and porous lithium iron phosphate electrodes
(Peer reviewed; Journal article, 2023)We report Peltier heats and reaction entropy of cells with lithium metal- and near fully lithiated lithium iron phosphate (LFP) electrodes. The Peltier heats were measured through the Seebeck coefficient of thermogalvanic ... -
Seebeck coefficients of cells with lithium carbonate and gas electrodes
(Journal article; Peer reviewed, 2015)The Seebeck coefficient is reported for thermoelectric cells with gas electrodes and a molten electrolyte of one salt, lithium carbonate, at an average temperature of 750 °C. We show that the coefficient, which is 0.88 mV ... -
Tailoring nanopores within nanoparticles of PtCo networks as catalysts for methanol oxidation reaction
(Journal article; Peer reviewed, 2017)It has been recently reported that engineering the pores within alloy nanoparticles leads to improvement in the electrochemical activity of nanoparticle catalysts due to the enhanced electrochemical active surface areas. ... -
Tailoring the oxide surface composition of stainless steel for improved OER performance in alkaline water electrolysis
(Peer reviewed; Journal article, 2022)There is a strong desire to replace bulk nickel electrodes for oxygen evolution reaction (OER) with a cheaper and more active steel material in alkaline water electrolyser (AWE). However, implementing an activation procedure ... -
Three-dimensional hierarchical walnut kernel shape conducting polymer as water soluble binder for lithium-ion battery
(Journal article; Peer reviewed, 2018)Hierarchical nanostructures containing three-dimensional (3D) spheres are promising materials due to their unique physicochemical characteristics. In this study, a 3D hierarchical walnut kernel shape conducting polymer ... -
Unlocking Room Temperature Formation of Li-Rich Phases in Aluminum Anodes for Li-ion Batteries
(Journal article; Peer reviewed, 2024)Aluminum (Al) has been an attractive anode candidate for lithium-ion batteries (LIBs) since the 1970s. While the formation of β-LiAl is considered the origin of the Li storage capability in Al anodes, multiple Li-Al phases ...
