Water electrolysis on the 3D nickel foam catalyst using solar energy

The aim of the investigation was to construct and test an alkaline water electrolyzer with nickel foam as a new type of electrode material. A 30 W photovoltaic module (PV) was used as a power source. Potential-current characteristics of the electrolyzer under natural and force flow circulation as well as the PV module maximum power point trajectory are determined. The hydrogen evolution reaction (HER) was investigated on both foamy and polycrystalline nickel electrodes in a three-electrode reactor using dc and ac electrochemical methods. Improved catalytic activity of 3D nickel foam is attributed to the increased specific area. Mathematical models of the electrolyzer and photovoltaic module are given.
