Materials such as coal, biomass and household wastes are to be used as the anode depolarizers, in order to produce low cost hydrogen at the cathode. the electricity needed to evolve hydrogen is lowered from approximately 2 volts to about 1.2 volts, with a current density about 6mA cm/sup -2/ for acid-washed lignite slurries, 1 mA cm/sup 2/ for grass slurries and 0.3 mA cm/sup -2/ for household waste slurries electrolysis. The anodic products associated with the electrolysis are commercially valuable ones in such a way that they not only compensate for the cost of hydrogen production, but to an extent that hydrogen can be considered as a by-product. The natural of the anodic products associated with the electrolysis has been investigated. An examination of the difference between washed and unwashed coal was also made. An attempt was made to remove the ferrous content of the coal. The organics in coal, biomass and household wastes - derived liquid samples, were separated from the aqueous media. The samples were analyzed by N.M.R., gel permeation chromatography and high resolution gas chromatography-mass spectroscopy (GC/MS). The best method of analysis has been found to be gas chromatography-mass spectroscopy.
