Neutral electrolytes are needed for many artificial photosynthesis applications since the great majority of known semiconductors that can be used as light absorbers deteriorate quickly at excessive pH values. Additionally, pH-neutral electrolytes prevent a lot of the potential safety problems that could develop if more caustic electrolytes were used. Thus, there seems to a designing of a technology for this conventional electrolysis technique for water splitting. Therefore, the introduction of capillary- fed electrolysis cell. A capillary-fed electrolysis cell is a type of fuel cell that uses a capillary network to supply reactants to the electrodes. It is a type of proton exchange membrane (PEM) fuel cell, which generates electricity by reacting hydrogen and oxygen at the anode and cathode, respectively. The capillary-fed electrolysis cell has several advantages over traditional PEM fuel cells, including improved efficiency, reduced cost, and simplified system design. However, it also has some drawbacks, such as increased complexity due to the need for a capillary network, and potential clogging of the capillaries. Overall, the capillary-fed electrolysis cell is an innovative technology that shows promise for use in a range of applications, including portable power systems, backup power supplies, and stationary power generation. Capillary-fed electrolysis cells offer several advantages, including High Efficiency, Scalability, Low Operating Costs, Durability, Safety and Keywords. The benchmark catalyst is Pt/C and RuO2/ IrO2 for HER and OER, respectively. These materials not only have been in scarce, are also expensive.
