The importance of hydrogen as a fuel will steadily increase in future, mainly due to environmental necessities. Water electrolysis is the only proven technology for hydrogen production from nonfossil fuel primary energy sources. R& D on water electrolysis have been done to improve cell performance in efficiency and operating current density, since the energy crisis of 1973. Significant improvements have been made possible and further improvements are anticipated.This paper summarizes the design features of the following three major advanced electrolyzers the advanced alkaline water electrolyzer, the solid polymer electrolyte water electrolyzer and the high temperature water vapor electrolyzer.
