Calcination temperature dependent catalytic activity and stability of IrO2 – Ta2O5 anodes for oxygen evolution reaction in aqueous sulfate electrolytes
(Peer reviewed; Journal article, 2017) -
Comparing Anodic Bubble Behavior of Anodes from Anisotropic and Isotropic Cokes in Laboratory Scale Aluminum Electrolysis Cells
(Peer reviewed; Journal article, 2019)During production of aluminum in Hall-Héroult cells, carbon anodes electrochemically oxidize to form mainly CO2. The CO2 bubbles block the anode working surface during growth and coalescence, leading to cell voltage loss ... -
Correlating Oxygen Electrode Degradation to Cr Vaporization from Metallic Interconnects in Solid Oxide Cell Stacks
(Peer reviewed; Journal article, 2023)Symmetrical cells consisting of La0.58Sr0.4Co0.2Fe0.8O3-δ (LSCF) oxygen electrodes screen printed on both sides of a Ce0.9Gd0.1O2-δ (CGO) electrolyte were tested at 800 °C while being held close to a piece of Crofer 22 APU ... -
Electrode behaviors of Na-Zn liquid metal battery
(Peer reviewed; Journal article, 2017)The electroreduction processes on a Mo electrode in a Na-Zn liquid metal battery cell with a molten NaCl-CaCl2-ZnCl2 electrolyte were investigated at 565°C. The effect of the battery operating parameters on the loss rate ... -
In-Situ Monitoring of Interfacial Contact Resistance in PEM Fuel Cells
(Peer reviewed; Journal article, 2021)A new in situ method for measuring the interfacial contact resistance between the bipolar plate and gas diffusion layer of an operating PEM Fuel Cell has been developed. This method involves the insertion of probe wires, ... -
Influence of Electrode Gas Flow Rate and Solid Oxide Ratio in Electrolyte on the Seebeck Coefficient of Molten Carbonate Thermocell
(Peer reviewed; Journal article, 2017) -
Measuring In Situ Interfacial Contact Resistance in a Proton Exchange Membrane Fuel Cell
(Peer reviewed; Journal article, 2019)Interfacial contact resistance (ICR) is one of the remaining hurdles for successful implementation of stainless steel bipolar plates in PEM fuel cells. We have developed a reliable method, using thin gold wires, to measure ... -
Modeling Contact Resistance and Water Transport within a Cathode Liquid-Fed Proton Exchange Membrane Electrolyzer
(Peer reviewed; Journal article, 2023)Conventional proton-exchange membrane (PEM) water electrolyzers use thicker membranes (>175 μm) than their PEM fuel cell counterparts (<25 μm), which reduces hydrogen crossover but also reduces electrolyzer efficiency due ... -
Progress in Understanding Initiation of Intergranular Corrosion on AA6005 Aluminum Alloy with Low Copper Content
(Journal article; Peer reviewed, 2019)As part of an extensive research program to study recent, unexpected intergranular corrosion (IGC) on 6xxx series aluminum alloys (AlMgSi), this paper investigates the mechanism of initiation and early propagation of IGC ... -
Recycled Aluminium Alloys and their Models: Role and Behaviour of Alloying Elements during Alkaline Etching
(Peer reviewed; Journal article, 2023)Alkaline etching is a common pretreatment for aluminum surfaces. Etching behavior was compared between an alloy based on post-consumer scrap (PCS) and several model alloys of rolled AA3005 and extruded AA6060 with ... -
Removal and recovery of indium from ITO coated glass and scraps using molten salt electrolysis
(Peer reviewed; Journal article, 2019)Indium is an important strategic resource due to the scarcity for the metal. In the present study, molten salt electrolysis is used to reduce indium from ITO coated glass and scraps in order to seek a new way to recycle ... -
Ta-ITO Coated Titanium Bipolar Plates for Proton Exchange Membrane Water Electrolyzers
(Peer reviewed; Journal article, 2022)A novel bi-layer coating composed of a tantalum base layer with an Indium Tin Oxide (ITO) top layer was applied to titanium substrates. Samples were polarized ex situ in a parameter study, where the pH, potential and ...
