ABSTRACT
Technological advances in electronic industry have made portable consumer electronics like smartphones and other handheld devices serve various needs in human life, consequently resulting in demand for long-lasting portable power sources to support these gadgets. Fuel cells have earned significant interest because of their promising prospects as power sources. They offer a long lifetime and almost instant recharging combined with the benefits of high specific energy density, good efficiency, and environmental benignity. To expand their application prospect especially for portable applications, flexible fuel cells are being looked into with greater interest since the past decade. For flexible fuel cells to be commercially viable, the cell architecture and materials should be suitably chosen to remain flexible without compromising performance. In this regard, several researchers focus on designing and nanostructuring various materials as components to enhance fuel cell performance. The unique electronic and structural properties of low-dimensional materials especially 2-dimensional (2D) materials offer unique nano-size effects such as enhanced surface area, hydrophilicity, and better interaction with supported metal particles. This book chapter aims to discuss the recent advances and developmental strategies for 2D materials to be employed toward flexible fuel cells focusing on catalysts and supports in addition to materials and architecture.
