Summary Aerogel is known as one of today's 10 advanced structures that have earned a special place in industry or research based on its very high porosity, high active surface area, and low density. There are various methods that can be used to produce it as well as make it easily produced in bulk as subtopics in this paper in Section 2.0. At present, aerogels are widely used in catalytic applications, energy storage, photocatalysts, membrane separation, and fuel cells. Aerogel application in fuel cell has been discussed in Section 3.0 which include carbon‐based aerogel, graphene‐based aerogel, other aerogel based, and non‐noble catalyst with aerogel. This article is a reference for researchers to identify the advantages and opportunities available to lower costs and improve the performance of fuel cell systems that rely heavily on cost‐rich catalysts such as platinum. Opportunities and challenges in developing aerogel structures in the future are also explained in Section 5.0 in this paper.

The bio-electron-Fenton system integrates microbial fuel cell and Fenton process into a single system to destroy the organic and bio-refractory contaminants in wastewater. Its performance is closely dependent on the sufficient electron supplement by the oxidation process in anode chamber and the reduction process in cathode chamber. This article presents a novel cathode of a bio-electron-Fenton system which can simultaneously achieve good electron supplement and the wastewater treatment in cathode chamber. The cathode consists of indium-tin-oxide conductive glass on which layers of graphene-poly(vinyl alcohol) composite are sprayed by electrospinning. The material characterization is verified by Fourier transform infrared spectroscopy, scanning electron microscopy, and transmission electron microscopy. The voltage, current, and power density of the system are verified by cyclic voltammetry. The wastewater treatment is verified by dye decolorization. With the addition ratio of 4 wt% graphene, the system achieves the optimal power density of 74.1 mW/m 2 , open-circuit voltage of 0.42 V, and the decolorization of reactive black 5 of 60.25%. By constant-resistance discharge testing within three-cycle, the system can stably supply a maximum voltage of 0.41 V or above. Hence, the proposed electrospun graphene-poly(vinyl alcohol) composite cathode electrode can not only improve the power-supply efficiency but also enhance the efficiency of wastewater treatment.
