A fuel cell is an electrochemical device that converts the chemical energy of a fuel and oxidant into electricity. Cation-exchange and anion-exchange membranes play an important role in hydrogen fed proton-exchange membrane (PEM) and anion-exchange membrane (AEM) fuel cells, respectively. Over the past 10 years, there has been growing interest in using nanofiber electrospinning to fabricate fuel cell PEMs and AEMs with improved properties, e.g., a high ion conductivity with low in-plane water swelling and good mechanical strength under wet and dry conditions. Electrospinning is used to create either reinforcing scaffolds that can be pore-filled with an ionomer or precursor mats of interwoven ionomer and reinforcing polymers, which after suitable processing (densification) form a functional membrane. In this review paper, methods of nanofiber composite PEMs and AEMs fabrication are reviewed and the properties of these membranes are discussed and contrasted with the properties of fuel cell membranes prepared using conventional methods. The information and discussions contained herein are intended to provide inspiration for the design of high-performance next-generation fuel cell ion-exchange membranes.

This paper presents a novel architecture for a proton-exchange membrane (PEM) fuel cell stack, which is based on the concept that every cell in the stack works at the same condition and thus each cell has the same contribution to the overall output voltage and power. To meet this proposed requirement, special flow distributors were used to evenly distribute fuel and airflow to every fuel cell in the stack. Details of the flow distributor and experimental tests of a four-cell fuel cell stack are presented in the paper. The experimental results demonstrated the desired high performance of the fuel cell stack. It is proved that the novel architecture for fuel cell stack is successful and of significance to the development of high performance fuel cell stacks.
