Alkaline electrolyzer with nanostructured NiFeP electrodes for hydrogen production

Abstract

This paper presents an innovative Alkaline Water Electrolyser (AWE) based on using NiFeP nanostructured electrodes, from its initial design to its subsequent implementation, as suggested by the results of tests simulating the real-field operation of the electrolyzer. The nanostructured electrodes were fabricated by template electrosynthesis, a straightforward and cost-effective process. This fabrication method was analyzed by Life Cycle Assessment from an eco-design perspective. Electrochemical tests were conducted on the individual electrodes and the complete cell to evaluate their electrocatalytic properties in alkaline solution. The electrodes exhibited robust stability over an extended period (125 hours) with no discernible indications of performance degradation.
