The water penetration in one direction and the H+ migration in the opposite direction can be balanced so that the oxygen is produced free of water (Hamilton Sundstrand, 2003). The hydrogen gas still contains water that has to be separated through a cleaning stage. where such oils and other matter pass through a hot charcoal bed in the lower

2.1.3 Water electrolysis: reverse fuel cell operation The conversion of electric energy into hydrogen (and oxygen) by water electrolysis has been known for a long time (demonstrated by Faraday in 1820 and widely used since about 1890), but if the electricity is produced by use of fossil fuels, then the cost of hydrogen obtained in this way is
