![]() ![]() The internal states of these cells cannot be obtained by direct measurements and these states are usually affected by operating conditions such as temperature and noise. To achieve the high-voltage levels required for vehicular or utility applications, a supercapacitor pack should contain hundreds of high-capacity series-parallel cells. In this respect, supercapacitors have gained interest due to their unique features such as high power density, long lifespan, and wide operating range. This paper provided an alternative approach to achieve continuous hydrogen production, electricity generation and waste degradation using the supercapacitor assisted photocatalytic fuel cell system.Recent advances in energy storage systems have speeded up the development of new technologies such as electric vehicles and renewable energy systems. In addition, the system exhibited a good degradation capacity of ethylene glycol under illumination with the generation of electricity. The results suggested that the system can achieve a sustainable hydrogen production under illumination (32 μmol/L) and in dark (13 μmol/L), and an improved efficiency of the photoelectrocatalysis conversion with the chemical bias. ![]() To solve this issue, in this paper, we herein developed a green supercapacitor assisted photocatalytic fuel cell system with a chemical bias, which aimed for storing photoelectrons by supercapacitors (2 mg/cm 2) under light irradiation and discharging for hydrogen production under dark to enable continuous hydrogen production. However, hydrogen production can not be maintained due to intermittent illumination during a full-day. Photocatalysis for hydrogen production and pollution degradation is of significance for energy recovery and environment protection. ![]()
