Abstract
Sustainable and renewable energy sources are essential to reaching carbon neutrality on a global scale soon. In
addition to their potential for producing green energy, hydrogen fuel cells have drawn a lot of interest for their
ability to lower CO2 and SO2 emissions, which makes them perfect for usage in homes where people value
cleanliness above all else. Hydrogen fuel cells have been around for more than a century, but their general
implementation is limited by several technical issues and high costs, especially when it comes to membranes and
electrodes. Traditional designs, such as PEM hydrogen fuel cells, microfluidic membrane-less fuel cells, and solid
oxide fuel cells, have attempted to overcome these concerns by chemical, mechanical, and material advancements.
This paper presents a novel approach that uses an external electric field to improve the efficiency and functionality
of hydrogen fuel cells, resulting in the invention of the External Electric Field Membrane-less Hydrogen Fuel
Cell (EEFMLHFC). The proposed idea uses the notion of oriented external electrical field electrochemical
catalysis to accelerate and steer the ionic reactants—hydrogen and oxygen—towards one other, resulting in a
smoother and more efficient reaction. This design eliminates the requirement for a typical membrane while also
addressing common difficulties including water flooding, membrane breakdown, and material expansion caused
by different heat coefficients. The EEFMLHFC achieves excellent reactant adsorption and cell power production
by using porous platinum electrodes that are augmented by an external electric field and a water-cooling system.
