Hydrogen production through electrolysis and power generation through the fuel cell: an experimental and computational fluid dynamics study

Abstract

The most prevalent element found in nature is hydrogen. It functions as fuel that could be used in cells or as automotive fuel when it is in the diatomic state rather than just a gas. There are many ways to produce hydrogen, and the current effort focuses on one of them: producing hydrogen using electrolysis. The present study aims to determine the influence of various parameters such as electrode length, electrode diameter, electrode material, electrolyte concentration, and volume of the electrolyzer. The amount of hydrogen produced by the various compositions has been contrasted. The hydrogen yield has been found to be increase with increases in the electrolyte concentration and electrode length, but it has been found to be decrease with increases in electrode diameter. The graphite electrode has produced higher yield than the stainless steel electrode. The hydrogen produced by the system had been utilized as a source for the fuel cell module in the simulation tests, and it showed that the hydrogen electrolysis integrated with the fuel cell module may be able to generate power.
