Hydrogen is a potential candidate that can serve as a large-scale and long-term storage medium for renewable energy sources. Alkaline Water Electrolysis (AWE) is the only established and technically matured technology for the large-scale production of clean hydrogen. However, finding cost-effective and sustainable materials to design the critical components of alkaline electrolysis cells is still one of the pressing challenges of this technology. This paper presents an experimental study for hydrogen production by alkaline water electrolysis employing austenitic stainless steel electrodes (SS316, SS316L & SS310). The study at RGPV Bhopal intends to evaluate the field performance of AWE under examination by independently using the three sets of electrodes with normal and modified surface morphologies. The impact of surface morphology modification on the cell current density and hydrogen gas evolution rate is experimentally investigated for the three sets of electrodes. The electrolyzer is powered by an array of 0.9kWpamorphous silicon thin film(aSi-TF) P.V. modules. Integrating the aSi-TFPV array and the electrolyzer is done via a DC-DC converter developed for power conditioning and control.
Results reveal that surface morphology modification improves cell current and rate of experimental hydrogen production for all the three austenitic S.S. electrode specimens, with SS310 electrodes exhibiting better cell current values & gas production rates overSS316 & SS316L electrodes.
