Current status, opportunities, and challenges in fuel cell catalytic application of aerogels

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.
