Energy appears to be a fundamental driving force of economic and political strategies as well as planetary stability. Energy-related issues such as (1) the availability of new energy sources and viable technologies, (2) the disparity in access to energy sources, (3) the role of energy in our societies (energy societal metabolism), (4) the energy support to the life of our cities (where about half of world population is going to live very soon), and (5) the energy demand for food security all over the world, are "hot" problems that humans will have to face within the framework of...

Demand for fuel cell technology is growing rapidly. Fuel cells are being commercialized to provide power to buildings like hospitals and schools, to replace batteries in portable electronic devices, and as replacements for internal combustion engines in vehicles. PEM (Proton Exchange Membrane) fuel cells are lighter, smaller, and more efficient than other types of fuel cell. As a result, over 80% of fuel cells being produced today are PEM cells.

This new edition of Dr. Barbir's groundbreaking book still lays the groundwork for engineers, technicians and students better than any...
