In this work, we investigated the effects of electrode gap spacing on the amount of hydrogen produced in Aluminium/Copper Fuel Cell and its efficiency. Aluminium/Copper materials were used as the electrodes because of their high performance in the electrolyser systems while Potassium Hydroxide (KOH) was used as electrolyte. 10% concentration of potassium hydroxide was used throughout the experiment. The electrode spacing of 5mm and 10mm were used. It was observed from the graph that 5mm electrode spacing produced maximum efficiency of 29.7% and 10mm electrode spacing produced 17.7% efficiency. This implied that hydrogen production was highly dependent on electrode gap distance. The smaller the gap between the pair of electrodes, the more hydrogen was produced and the more efficient is the system.
