Hydrogen is envisioned as the most promising alternative to conventional fossil fuels with less environmental damage, and greater conversion efficiency. And, fuel cells are no doubt the key for widespread implementation of hydrogen.

Among several methods, hydrogen can be produced by water electrolysis with a higher degree of gas purity and increased level of safety. Furthermore, water electrolysis based on proton exchange membrane (PEM) offers several advantages over traditional technologies including greater energy efficiency, higher production rates, and more compact design. ....more
