Abstract
With emerging demand of potable and wearable electronic devices, reliable and flexible energy suppliers are
inevitable. Polymer electrolyte membrane fuel cells (PEMFCs) attract great attention due to high energy density
and sustainability. However, non-bendability limits their application in flexible electronic devices. To make
PEMFCs adaptable and flexible, considerable efforts have been devoted to developing various bendable com-
ponents or advanced techniques. This review, therefore, focuses on the advancement of components and relative
techniques of flexible PEMFCs, which determine the performance and durability, while achieved little concern in
other reviews. The components and techniques include membrane, flexible catalytic layer, flexible gas diffusion
layer, flexible bipolar plates, assembly of single cell or stack, store or supply of fuel and oxidant. In each section,
the materials or techniques commonly used in conventional PEMFCs are summarized firstly, followed by the
reasons why they aren’t appliable to flexible PEMFCs and then proceeding to the development of flexible
components and relevant techniques of flexible PEMFCs. Subsequently, the flexible PEMFCs’ performance and
durability are presented, reaching to 100–200 mW cm and dozens of hours, respectively, still far lower than
those of conventional PEMFCs. Finally, a brief perspective on remaining challenges and future development of
flexible PEMFCs are provided
