Vanadium | V (Element)
Vanadium was discovered by Andrés Manuel del Rio, a Spanish chemist, in 1801. Rio sent samples of vanadium ore and a letter describing his methods to the Institute de France in
Periodic Table of Elements: Los Alamos National Laboratory
Pure vanadium is a bright white metal, and is soft and ductile. It has good corrosion resistance to alkalis, sulfuric and hydrochloric acid, and salt water, but the metal oxidizes readily above 660°C.
Vanadium Oxygen Fuel Cell Utilising High Concentration
A vanadium oxygen fuel cell is a modified form of a conventional vanadium redox flow battery (VRFB) where the positive electrolyte (VO2+/VO2+ couple) is replaced by the oxygen
