The Influence of Magnetic Field on Newly Designed Oxyhydrogen and Hydrogen Production by Water Electrolysis

Abstract

Herein, new prototypes of a dry cell and an H2 generator are designed to produce hydrogen and HHO (oxyhydrogen) gas, and the effect of a magnetic field on both systems is examined. Experiments are conducted in both systems; a 3.5% potassium hydroxide electrolyte is chosen because it is an alkaline type of solution with a high dissociation rate. NdFeB magnets with magnetic fluxes of 1.2 and 1.6 T are added to both systems to reveal the effect of the Lorentz force on gas production. The flow rates of HHO gas in the productions under 1.2 and 1.6 T in the HHO system are 680 and 730 ml min−1, respectively. These values show that the flow velocities were 15.4% (1.2 T) and 23% (1.6 T) greater, respectively than the values recorded without a magnetic field (MF). Additionally, the percentage of hydrogen production increased by 4% for 1.2 T and 11% for 1.6 T compared to the measured value without the MF. In addition, production costs are calculated for both systems in the study: the energy required to obtain the same flow rate as the comparison examples in the literature was lower.

Modeling of Artificial Neural Networks for Hydrogen Production via Water Electrolysis

“…For hydrogen production from water splitting, there are water electrolysis (WE) processes available, including alkaline WE, proton exchange membrane WE, solid oxide WE, and alkaline anion exchange membrane WE [4]. Typically hydrogen production via WE is the process of converting water into hydrogen and oxygen by passing a direct current from the cathode and anode electrodes in the electrolyte to each other [4,5,6,7].…”

Enhancement of hydrogen production using dynamic magnetic field through water electrolysis

“…However, perpendicular magnets with different poles generate swirling locomotion of bubbles, which enforces bubble detachment in lower current density 31 . Despite the bubble formation control, Lorentz force gives positive impact on rising the flow rate of hydrogen (H 2 ) and oxyhydrogen (HHO) gas by 23% 32 . Therefore, the control of MHD phenomenon and hydrogen gas flow can be obtained through dynamic magnetic field (DMF) exposure.…”

H2 Production of As‐Cast Multialloying Mg‐Rich Alloys by Electrochemical Hydrolysis in NaCl Solution

“…[23,24] In addition, the development of effective H 2 generation technology with low consumption of energy and materials is another tough question. Nowadays, H 2 generation through water, including electrolyzed water, [25,26] photolysis water, [27,28] and alloys hydrolysis, [29] is proposed. The large energy consumption and lack of effective catalysts are the main bottlenecks to electrolyze water.…”
