Abstract: This article reviews the applications of MXene materials used in fuel cells. MXene is a new family of two-dimensional transition metal carbides and carbonitrides materials. This kind of materials can usually be produced by etching the A element from the MAX phases. For the good electrical conductivity, hydrophilicity, transparency and flexibility, MXenes will be good candidates in the fields of catalysis, energy storage, composite materials, sensor, antibiosis and so on. The synthetic methods, structure, chemical stability and electronic characteristics of MXenes are briefly introduced in this paper. The applications of these materials in fuel cells are summarized, especially as Pt catalyst supporters. MXene supported Pt catalysts exhibit high activity and stability for oxygen reduction reaction. At the end of the article, some problems and challenges of MXene used in fuel cells and as catalysts supporters are proposed.

Key words: MXene, Pt catalyst, fuel cell
