Hydrogen, a clean energy carrier, is the most abundant chemical element in the universe, accounting for 75% of normal matter by mass and over 90% by number of atoms. When hydrogen gas is oxidized electrochemically in a fuel cell system, it generates pure water as a by-product, emitting no carbon dioxide. Hydrogen has emerged as a new

Read MoreThe voltage (cell potential) of a dry cell is approximately 1.5 V. Dry cells are available in various sizes (e.g., D, C, AA, AAA).All sizes of dry cells comprise the same components, and so they exhibit the same voltage, but larger cells contain greater amounts of the redox reactants and therefore are capable of transferring correspondingly greater amounts of
Read MoreA battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity. In this section, we describe the chemistry behind some of the more
