Special Issue Information

Dear Colleagues,

To build on the success of the Special Issue in Polymers, "Polymeric Materials for Electrical Applications ", and to continue our research into this popular topic, we are pleased to open the second volume of this Special Issue. The aim of this Special Issue is to collect research and review papers. This Special Issue discusses the development of polymer electrolyte membranes and new materials for electrical applications. All relevant contributions to this Special Issue are welcome.

Alternative methods to generate electricity with high efficiency, minimal production of greenhouse gases, and reduced reliance on fossil fuels are desired to sustain a growing society. In this scenario, batteries and fuel cells have been proposed as potential candidates for various applications, such as transportation, distributed power, and portable devices. Polymer electrolytes are promising materials for a wide variety of applications in electrochemical devices, such as rechargeable batteries, supercapacitors, fuel cells, electrodes, and others. It is well known that ionic diffusivity in polymeric membranes is closely related to their structural dynamics controlled by the large-amplitude structural rearrangement of polymer segments, the transition temperature, and the rigidity and fragility of polymers. In this Special Issue of Polymers, we wish to bring together works that can be a reference for the industry for the present and future construction of devices using rechargeable batteries, supercapacitors, electrodes, catalysts, and fuel cells. This Special Issue is for researchers and technologists interested in all aspects of the science, technology, and applications of sources of electrochemical power. It will feature original research papers and reviews about materials science, with applications linked to batteries, supercapacitors, proton-exchange membrane fuel cells (PEMFCs) working at moderate and high temperatures, alcohol fuel cells (AFCs), phosphoric acid fuel cells (PAFCs), solid oxide fuel cells (SOFCs), molten carbonate fuel cells (MCFCs), microbial fuel cells (MFCs), and photo-electrochemical cells. Topics considered include the research, development, and applications of materials and novel components for these devices.

The study of the electrochemical catalyst conversion of renewable electricity and carbon oxides into chemical fuels attracts a great deal of attention by different researchers. The main role of this process is in mitigating the worldwide energy crisis through a closed technological carbon cycle, where chemical fuels, such as hydrogen, are stored and reconverted to electricity via electrochemical reaction processes in fuel cells. The scientific community focuses its efforts on the development of high-performance polymeric membranes together with nanomaterials with high catalytic activity and stability in order to reduce the platinum group metal applied as a cathode to build stacks of proton exchange membrane fuel cells (PEMFCs) to work at low and moderate temperatures. The design of new conductive membranes and nanoparticles (NPs) whose morphology directly affects their catalytic properties is of utmost importance. Nanoparticle morphologies, like cubes, octahedrons, icosahedrons, bipyramids, plates, and polyhedrons, among others, are widely studied for catalysis applications. The recent progress around the high catalytic activity has focused on the stabilizing agents and their potential impact on nanomaterial synthesis to induce changes in the morphology of NPs.
