Electrode Performance in Reversible Solid Oxide Fuel Cells
Olga A. Marina,Larry R. Pederson,Mark C. Williams,Greg W. Coffey,Kerry D. Meinhardt,Carolyn D. Nguyen,Ed Thomsen +6 more
TL;DR: In this article, the authors proposed a reversible fuel cell, which is capable of operating both as a fuel cell and as an electrolyzer, although the fuel cells and electrolyzer functions are carried out in separate subsystems.
1 kW/1 kWh advanced vanadium redox flow battery utilizing mixed acid electrolytes
Soowhan Kim,Edwin C. Thomsen,Guanguang Xia,Zimin Nie,Jie Bao,Kurtis P. Recknagle,Wei Wang,Vilayanur V. Viswanathan,Qingtao Luo,Xiaoliang Wei,Alasdair Crawford,Greg W. Coffey,Gary D. Maupin,Vincent L. Sprenkle +13 more
TL;DR: In this article, a vanadium redox flow battery (VRFB) using a newly developed mixed acid (sulfuric and hydrochloric acid) supporting electrolyte at a kW scale was demonstrated.

Copper Doped Lanthanum Strontium Ferrite for Reduced Temperature Solid Oxide Fuel Cells
TL;DR: Copper doped lanthanum strontium ferrite (LSCuF) showed superior kinetics for the electroreduction of oxygen as mentioned in this paper, which was confirmed with cyclic voltammetric studies on half cells and on full fuel cell tests.

Wetting of sodium on β''-Al2O3/YSZ composites for low temperature planar sodium-metal halide batteries
David Reed,Greg W. Coffey,Eric S. Mast,Nathan L. Canfield,Jirgal Mansurov,Xiaochuan Lu,Vince L. Sprenkle +6 more
TL;DR: In this paper, the sessile drop technique was used to investigate the effects of moisture and surface preparation on the performance of planar β-Al2O3 composites at low temperature.

TL;DR: In this article, a planar NBB button cell was proposed to reduce the area of specific resistance and operate at lower temperatures. But the lower operating temperature allows for use of more cost-effective cell materials and decreases adverse temperature effects that impact cycle life and overall cost.
