NASF/AESF Foundation Research Project #123: Electrochemical Manufacturing for Energy Applications – 3rd Quarterly Report - Part I

This is the third quarterly report, covering work during July-September 2022 and consists of a review, “Formidable Challenges in Additive Manufacturing of Solid Oxide Electrolyzers (SOECs) and Solid Oxide Fuel Cells (SOFCs) for Electrolytic Hydrogen Economy toward Global Decarbonization,” prepared and submitted to the peer-reviewed Ceramics Journal for publication. What follows here is Part I of the review paper, covering the literature on additive manufacturing of SOFCs and SOECs. Part II, covering opportunities and challenges for additive manufacturing technologies, will be published in January 2023.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 6th Quarterly Report

The NASF-AESF Foundation Research Board has selected a project on addressing the problem of PFAS and related chemicals in plating wastewater streams, studying PFAS destruction via electrooxidation and electrocoagulation. This sixth quarter report covers the continued assessment of eight perfluoroalkyl acids PFAAs most commonly found in wastewaters, by electro-oxidation with a Magnéli phase Ti4O7 anode across a range of anodic potentials in solutions, exploring the reaction mechanisms. To summarize, the PFAAs start to exhibit degradation behavior when the anodic potential reaches a level where water oxidation occurs, suggesting that the hydroxyl free radicals generated via water oxidation play a role in PFAA degradation.
