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.

Microfluidic Fuel Cell

The development of microfluidic and nanofluidic devices is gaining remarkable attention due to the emphasis put on miniaturization of conventional energy conversion and storage processes. A microfluidic fuel cell can integrate flow of electrolytes, electrode-electrolyte interactions, and power generation in a microfluidic channel. Such microfluidic fuel cells can be categorized on the basis of electrolytes and catalysts used for power generation. In this work, for the first time, a single microfluidic fuel cell was harnessed by using different fuels like glucose, microbes and formic acid. Herein, multi-walled carbon nanotubes (MWCNT) acted as electrode material, and performance investigations were carried out separately on the same microfluidic device for three different types of fuel cells (formic acid, microbial and enzymatic). The fabricated miniaturized microfluidic device was successfully used to harvest energy in microwatts from formic acid, microbes and glucose, without any metallic catalyst. The developed microfluidic fuel cells can maintain stable open-circuit voltage, which can be used for energizing various low-power portable devices or applications.

Critical Issues

Proton exchange membrane (PEM) fuel cells are among the most promising fuel cell technologies. Recent experimental and numerical investigations [1–3] on PEM fuel cells (PEMFC) identified water management as one of the most critical issues for designing robust, high-performance PEM fuel cells. Proper water management within the cell is therefore essential, as dehydration of the membrane or flooding of the cathode result in increasing resistive losses. Flooding reduction in the fuel cell is commonly done by removing water with excessive reactant (H2 or O2) flow rates and elevated gas pressures. This mixture makes air delivery the largest parasitic load on fuel cells. Typically, this type of air delivery consumes more than 20% of the fuel cell power. As an alternative, we have developed a novel biased AC electroosmtic micropump for PEM fuel cell applications that can be fabricated with micro-electro-mechanical-systems (MEMS) compatible semiconductor micro-fabrication. This research paper will experimentally demonstrate the bi-directional pumping action that can prevent flooding, increase power density, and ensure stable performance of fuel cell by removing water from flooded regions and redistributing it to under-saturated regions.
