Fuel cells and hydrogen economy

open access: yesChemical Industry and Chemical Engineering Quarterly, 2005
Fuel cells with applications ranging from power generation to transportation need hydrogen as fuel. Hydrogen is not a source of energy, and hydrogen is not a readily available fuel. Hydrogen is more like electricity - an intermediary form of energy or an energy carrier.
