Characterization of a multi-electrode common-ducted HHO dry cell


Electrolytic production of hydrogen from water is gradually gaining its importance among the other conventional process of hydrogen production in the context of renewable energy source utilization and environmentally clean technology. The present work study hydrogen gas production in a form called Brown’s gas or HHO gas by alkaline water electrolysis with KOH as electrolyte in an 11 plate common-ducted HHO dry cell. The variation of HHO gas flow at different concentrations of electrolyte was investigated. During electrolysis the temperature of the electrolytic solution is also found to increase gradually with time due to overvoltages, which further effects the current, electrical and gas production rate. The effects of temperature on the HHO gas production rate and energy efficiency of electrolysis process are discussed.
