![]() This paper provided an alternative approach to achieve continuous hydrogen production, electricity generation and waste degradation using the supercapacitor assisted photocatalytic fuel cell system. In addition, the system exhibited a good degradation capacity of ethylene glycol under illumination with the generation of electricity. Power of the battery is limited by a rate limiter block, therefore the transient power is supplied to the DC bus by the supercapacitor. The supercapacitor is connected to a Buck/Boost converter and the battery is connected to a Boost converter. 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. The circuit illustrates a simple hybridization of a supercapacitor with a battery. 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. ![]()
