This chapter introduces steam electrolyzers for hydrogen production, beginning with the basic principles of operation. This is followed by a discussion of the types of cell components generally used and in commercially available devices, particularly the electrolyte and electrode materials. The efficiency is also explored. The use of alkaline water electrolysis in industry is discussed, and finally recent trends in research are explored.
