This review focuses on the role of hydrogen technologies in transition from petroleum production to new fuel to power transportation system. At present, the looming crisis caused by the decline in petroleum production and the need to control greenhouse gas emissions exemplifies the need for new energy solutions. The key component of a hydrogen-powered transportation sector will be the proton exchange membrane (PEM) fuel cell. PEM fuel cells use hydrogen and oxygen to generate electricity, with water and heat as by-products of the electro-chemical reaction. The review also discusses that to compete favorably with internal combustion engines and hybrid cars, PEM fuel cells need to address several issues, including performance, durability, and cost. Hydrogen from natural gas could provide a firm stepping stone as the energy system evolves away from petroleum.
