Abstract

Hydrogen production via electrolysis of water (water-splitting reaction) is a means of storing excess electrical energy produced by renewable energy sources. This hydrogen gas may be used directly to produce power via combustion or recombination with oxygen in a fuel cell, it may be injected into the natural gas network, and it may be used as a transport fuel or as a chemical intermediate. The main methods of hydrogen production via electrolysis are described: alkaline, proton exchange membrane, and solid oxide. The materials of construction and the advantages and disadvantages of each system are ...
