Fuel cell. Fuel cells are a type of energy conversion technology which take the chemical energy contained within a fuel and transform it into electricity along with certain by-products (depending on the fuel used). [1] It''s important to note that fuel cells are not heat engines, so they can have incredibly high efficiencies.

With the increasing demand of electrochemical energy storage, Titanium niobium oxide (TiNb 2 O 7), as an intercalation-type anode, is considered to be one of the most prominent materials due to high voltage (~1.6 V vs. Li + /Li), large capacity with rich redox couples (Ti 4+ /Ti 3+, Nb 4+ /Nb 3+, Nb 5+ /Nb 4+) and good structure stability..
